The Laws of Wealth

You are meant to be a poor investor. Human nature is stacked against you. If you want to understand why, read The Laws of Wealth by Dr. Daniel Crosby. But don’t despair. If you want to be a better investor, give a copy of The Laws of Wealth to your financial advisor, and hold him accountable for following a Rules Based Investing system like the one proposed by Dr. Crosby.

This is an interesting and enjoyable book. If you are a student of behavioral finance, you’ll recognize a large portion of the topics covered by Dr. Crosby. Everyone will enjoy the way he points out our flaws, and the real life stories behind them. Dr. Crosby lists ten rules of investing, and summarizes how to think about each one. The final step is to build a rules based system for investing, to defeat our bad habits, and provide the best chance for success. But there’s a catch. Knowing and understanding the rules aren’t enough. Rule #2 shows how you cannot do this alone. The best use of this book, is as a bridge between investor and advisor.

I’ve managed client money as a financial advisor for over sixteen years. I was familiar with Dr. Crosby’s rules, perhaps in different form, but I still benefited greatly from this book. Although I knew the rules, I didn’t always know how to communicate them to clients. Since reading The Laws of Wealth, I’ve used examples from the book to influence client behavior for their betterment. I’ve given a copy to my junior advisors, and I encourage other financial advisors to leverage Dr. Crosby’s unique skill set to provide better advice to their clients.

First Thoughts on Trump

Conventional wisdom was that he could not win. Critics said he was all personality, with no substance. He could mesmerize a crowd with calls for change, but he could not be trusted to hold the office. Half the electorate hated him. Moreover, he was going up against one of the most experienced politicians of our lifetime: a Senator and a hero to many.  Any yet, he did win. Afterwards, his opposition was flummoxed. How could this have happened? What is wrong with our country that they would do this? Financial markets had an immediate negative reaction, but fortunately, that quickly ended.

On November 4, 2008, Barack Obama was elected President of the United States.

This week, the Republican's version of Obama, Donald Trump, repeated the process. 

Trump is Obama. They share the same skills. Both are highly persuasive, attractive men of vigor. They share the same weaknesses. Trump had no political experience, while Obama had no "real life" experience. Both were polarizing, especially on racial issues. And in the end, both won by defeating political dynasties (they each beat both the Bush and Clinton cartels). 

So if you were a fan of Obama, perhaps you can admit a little familiarity for how Trump fans feel in victory. If you are a Trump supporter, perhaps you'll recall how McCain fans felt in defeat. Perhaps both sides can find a little empathy.

P.S. If you think this election is different because no one predicted Trump, take a look at what they said about Obama in 2008.

Will Kassouf, Man on the Margin

If you follow poker, you're probably aware of the ruckus caused at the World Series of Poker (WSOP) this year by Will Kassouf. He is a man on the margin.

Marginality is an economics concept. The best way to understand it is through the maxim "all change takes place on the margin". If you load ten thousand straws on a camel, but then break the camel's back with the ten thousand and first, the last straw is the marginal straw. Importantly, that last straw was no different than the others. Not better, not worse. Not good, not bad. Not first, but often, and in the case of the straw, last. One of my influences, Jude Wanniski, used to write a daily memo, for years, pointing out a marginal impact worthy of further discussion. {My favorite is the Wired Interview with Peter Drucker. The most analogous to Kassouf might be the piece he wrote on Terri Schiavo's legal limbo and the dollar value of a human life.} I see such a point in Will's behavior at the WSOP Main Event. 

Live poker is going to change because of Will, and the reactions he elicits from players, dealers, and poker supervisors. Perhaps implementation of a clock system will be accelerated. Perhaps the rules on disruptive behavior, stalling, or talking will be revised. One change I would like to see discussed is some formalization of how supervisors (floor personnel) communicate with a table full of players. The primary criticism against Kassouf (which is legitimate as far as I can tell) concerns how his behavior was unfair to the majority of other players (at least at his table). This will no doubt be debated in the coming weeks and months. On the other hand, most civil systems designed to carry out justice generally are arranged to protect the individual from abuse by the authority or the mob majority. I hope there will a similar debate about how the other players coordinated and argued against Will to the authority (supervisor). How does an accused get a "fair trial" when the supervisor is called to adjudicate? Also, how does poker ensure a fair treatment for amateurs who stand accused by a group of professionals (who often are granted trusted status by supervisory personnel)?

The point of identifying Will as a Man on the Margin is not to support him or his antics. I'm merely saying he was polarizing enough, on a meaningful issue for poker, that his actions will lead to much discussion and possible changes in the game. For what it's worth, my personal opinion is that Will's behavior is annoying. I don't play enough or understand the rules enough to have an opinion on the legality of his approach. Watching the edited coverage, I was more disappointed by the behavior of the surrounding professional players than I was by Will's antics. I had no opinion of Will leading up to the events, but I had very positive opinions of many of his opponents, and they did not show themselves very well. 


Don't Vote, It Just Encourages Them

It's a highly contentious election cycle, and as usual, politics is a common topic of conversation. In conversations (online or in person), I have expressed my opinions about the presidential election, but my most controversial opinion is apolitical. I don't vote. When I tell others my position, I get more confusion and disagreement than any other political view I hold. Being unconventional can be fun, but alienating.

To be more clear, I have voted in the past, I may vote in the future, but my default is to not vote. I've written briefly on this before, but given how my recent conversations have gone, I think a longer explanation is needed.

The primary reason I rarely vote, is the same reason I rarely play the lottery: I understand math. The expected return on a lottery ticket is usually negative. Players should expect to lose money. This only changes when the lottery rolls over multiple times, and the prize pool gets to be enormous. Then, I play. Voting is similar, in that it has a negative expectation. It takes time, and time is money. Yet there is no return for any individual voter unless their vote changes the outcome. In other words, if my vote won't change the outcome, there's no value to me personally in voting. (There is valuing in signalling, but those can be had without actually voting.) A brief review of history reveals this rarely happens. When single-vote margins of victory occur, they are typically in very small turnout elections, like city commissioner in a small town. Thanks to the electoral college, they're basically impossible in the election for president. 

This reasoning is very clear, yet it provokes very strong reactions. Most opposition takes the form of "what if everyone thought that way?" Well, if a frog had wings, it wouldn't bump its ass while hopping. In other words, that's not the world we live in. If I found myself in that world, I'd adapt. If no one voted, I'd vote, and pick the leaders I want. The problem is an assumption about extremes. Conventional wisdom says voting is more accurate when everyone votes. That's nonsense. Voting is about sampling. It is like a blood test. The next time you have blood drawn, ask the doctor why he doesn't draw all your blood, to get a more accurate test. A small representative sample is all that is needed for an accurate outcome. So, if my views and opinions are properly represented within the pool of people who do vote, there's no need for me to do so.

A second reason I don't usually vote is humility. I have no idea who (or what skills) would make a good president (or senator, or mayor). In fact, my history suggests I am awful at this. Not only have I voted with the winner only once in a presidential election, but I've expressed severe dissatisfaction with every successful politician I've experienced at any level of government. This is kind of like investing in the stock market. You can try to outwit everyone else, and pick winners, or you can sit passively by and accept the decisions of those with skin in the game. I am a passive voter. 

The most common objection I receive to this view is that voting is a civic duty. Others claim it is a requirement for participating in the national discussion. I'm told "if I don't vote, I can't complain", and similar nonsense. Voting is my right, and it remains my right regardless of my participation. Having an opinion about the outcome is also a right, and it remains regardless of my participation in the right to vote. More importantly, the psychology of acting makes us biased. Once you vote, you join a team, and that makes is much less likely you can evaluate your own team objectively in the future. For example, how many who voted for Bush were openly opposed to his wars? How many who voted for Obama were openly opposed to the ACA healthcare law. Commitment is a powerful persuasive force, well documented in the psychology research. 

Don't vote, it just encourages them.


Thoughts on a Low Return Environment

The U.S. stock market valuation is at an extreme. According to NASDAQ, the ratio of the median stock price to revenue (price to sales) is at an all time high; higher than the internet euphoria of 1999 and the real estate boom of 2007. Federal Reserve policy is the primary reason for these high prices. A series of Quantitative Easing (QE) programs and Zero Interest Rate Policy (ZIRP) helped create record low yields. The slow growth economy creates few opportunities for corporate growth and innovation. Instead, corporate boards have been borrowing cheaply to repurchase their stock in record amounts, pushing market valuations to the current peak.

A recent Callan study highlighted in the Wall St. Journal focused on how these valuations may impact investors. In 1995, investors could expect a 7.5% average return from a simple portfolio of 100% bonds. By 2005, the same 7.5% return would require roughly 50% bonds and 50% stocks. At the end of 2015, the same 7.5% expected return would require 41% U.S. stocks, 22% foreign stocks, an 25% combined in real estate and private equity. Despite better diversification, the goal of a typical market return now requires much more volatility. Taking volatility as risk, this means the REWARD/RISK ratio is only 1/3 as attractive now as it was in 1995.

Higher overall volatility means a less certain, wider range of outcomes for investors. Variation in returns has two drawbacks. First, investors hate losses more than they love gains. Behavioral psychologists have labeled this mental bias MYOPIC LOSS AVERSION. “Myopic” because we are all hardwired to worry about the short-term effect of our actions. And “loss aversion” because we regret losses, two to 2 1/2 times more than we enjoy gains of a similar size. Second, outcomes depend on compound returns, not average returns. The returns in the Callan example are average annual returns, whereas compound returns are the net result of multiple years of returns. Here, a shortcut reveals the problem. Compound returns are roughly equal to average returns minus half the volatility. In the Callan study, average return is constant, but expected volatility is nearly three times higher today than 1995.

This is why protecting the downside is so vital. If you miss out on the upside it is not as detrimental as missing to the downside (psychologically or financially). One of my favorite fund managers, Eric Crittenden of Longboard, has a great example of the importance of absolute returns over beating or matching a benchmark. Given the following choices, which would you pick? Choice A: Outperform S&P 500 by 10x.
Choice B: Underperform S&P 500 50% of the time. Choice A is the obvious answer. In reality, both are the same strategy, that of Warren Buffett's Berkshire Hathaway. From 1985-2015, it crushed the S&P 500 yet trailed the index over 50% of the time on a daily basis. At one point during the streak, Buffet was 60% behind the index. Great long-term compound returns require investors to ignore the market benchmark in the short term, especially when valuations are high.

Short Review: Louie CK in Atlanta

Louie CK performed at the Fox Theater in Atlanta last night. The show seemed to be sold out, as one would expect. Louie CK is very popular, he only scheduled one show in Atlanta, and he hates for others to profit from his success, so he keeps ticket prices low and actively thwarts secondary markets.

Getting to the Fox was a hassle, because Atlanta mismanages street parking. Getting inside the Fox was a hassle, as they were screening for weapons, and cameras. The beer lines were long, partly because the barkeeps didn't seem to know what they were doing. However, they did well enough for some folks to be shit-faced. On a trip to the bathroom late in the show, I encountered a young man puking. I've seen that plenty at music shows, but never a comedy show, until now.

The show advertised an 8PM start. The lights dimmed about ten minutes after eight, and three unknown comics came out to warm up the crowd. The two guys were decent, but the woman was not funny. She was smart, and her jokes were clever and interesting. But not funny. Perhaps there's some psychology at work in my opinion. Both male comics (also white) primarily told self-effacing stories. The female comic also made fun of men. Psychologically, we let those like us joke or criticize us, but not outsiders. I don't claim to be immune to psychology, just honest in that she didn't entertain me.

The crowd was very diverse, except racially. There were very few blacks, which is interesting given Louie's start. And Louie did what he always does, he made fun of everyone. He told a racist joke, in order to mock those who tell racist jokes. He made fun of gays, in order to mock homophobes. He had a long series on teachers and education, in which he mocked teachers while praising them. When the crowd tried to applaud for teachers, he mocked the crowd. 

When Louie entered the stage, he didn't welcome the crowd or thank them, he simply launched into a bit on abortion. Over the course of his almost 90 minutes, he talked suicide, race, evolution, fucking, cocks, and children. Other than a bit about trying to teach math to teenagers, I had not heard any of the material before. Oh, and he wore a grey suit, white shirt, and a tie. No more black t-shirt and black jeans.

Overall a very funny night. I've seen most of his prior work, but it was nice to see Louie perform live. I recommend you do the same, if you get the opportunity.

Short Trip Report: Parx Poker

Getting There

I was near Philadelphia, in King of Prussia, for a work-related conference. I elected to stay an additional night so as to play some poker. There were other casinos around, but I was primarily interested in poker, and Parx has the largest room in the area.

Staying There

Parx is not a hotel, but there are several nearby, listed on the Parx website. I stayed at a Courtyard by Marriott, because I have frequent stay status there. The casino discount code listed on the Parx website didn't work, but my Marriott status got me almost as good a deal. Hotel staff discouraged me from walking, so I took Uber. When I saw how close it was, I decided I would walk back, unless it looked unsafe. I ended up playing until 3AM. I did walk back, without any incident. The surrounding area is mostly an office park, and it was a ghost town. 


The main casino has slots, table games, sports bar, and several food venues, but no poker. That is in a separate building. So, I registered to get a player's card, then quickly burned through my $10 in free slots. It was for the best that I went to the main room first. I never did see a player's card registration in the poker room, and the food choices are reduced there. I opted for the noodle house for dinner. I enjoyed a cold Asahi beer and good, hot, Pho soup with beef. 

Poker Room

If memory serves correctly, there were $1/2 and $1/3 NLHE games, as well as $5/5 PLO and $6/12 O/E games. At the time, $2/5 NLHE had the most tables running.  The room had a bar, lots of televisions, and over 60 tables. On this day, a Thursday while a tournament series was going on at Borgata, it was less than half full. Parx did run a nightly tourney for about $140. It was essentially a satellite structure, where 10% of the field got paid, but everyone who cashed received an equal split of the same prize money.  The room has food runners who will bring food to your table, but it was a limited menu. At one point in the night, several folks ordered the daily special, a chicken parmesan sandwich. I didn't eat anything there, but I did sample the beer and the coffee, which were both fine. Funniest food experience of the night was watching a pretentious regular try to order sushi for delivery from a local restaurant. It was a 2 1/2 hour ordeal but he finally received his raw fish. 

The Play

I don't play much poker, so normally I play $1/2 when in a strange place, but after circling the room a bit and observing, I decided to play $2/5. I bought chips, got on the list, and was seated within about 20 minutes. The rake at $2/5 was 10% to $5, plus a $1 bad beat drop.

No cash is allowed at the tables, which made adding on after a lost hand a bit of hassle, but I guess that's an incentive not to lose. The regulars were usually prepared for this, having large denomination chips on their person that they could put in play. An early hand at my table saw a big hand go down for about $1500 where a flopped nut flush stacks top pair, send nut flush draw. Afterward, the stacked player attempts to rebuy with an orange $1k chip. He asks the large stack to cash it for him, and there's a discussion about whether these chips are allowed to play at this level. Several players weigh in, outing themselves as regulars at Parx. The dealer declares the chip plays. Since he also periodically works as floor man, his decision is taken as final. As dealers come an go, the question comes up a few times, until the floor is called, and he rules that the $1k chips are not allowed at $2/5. Seems typical for many poker rooms that the rules depend on who you ask.

The most interesting hand of the night happened on a nearby $1/2 table. A regular who prefers PLO, sat to play with the stated objective of chasing the bad beat jackpot. He flops quad 6s. On the turn he gets it in against a straight flush draw, and loses. The bad beat was around $214k. Scuttlebutt put the table share at $13k. 

I didn't play many interesting hands, and when I did, I played poorly. I got involved in an unintentional 3-way all-in. I don't recall exact preflop action, but it had been raised and I got to the flop against a loose reg and a more ABC reg. Flop comes low (2d,5d,8x). I have 6d4d. Loose reg bets small, like 1/3 pot, so I raise, around 3.5X, and player on my left flats. Loose player then shoves for around $450 effective. He had done this several times prior, with simple over cards. He was slightly tilted, and was in a mode to bust or double up. He had been short, but after doubling twice, now had around 90bb. The player on my left, whose action seemed strong, was not acting strong. I felt good about calling the loose player and let that dominate my thinking. I called, as did the player on my left. Loose player had Ad3d, so he took all my flush outs. Player on my left had 7d,6s. I was left needing a 4 or 7. After two bricks, the loose player dragged it with A high. In hindsight, I should have adjusted loose player's range for having built his stack back up. I kept thinking the player on my left was just fishing, and he would go away, but he didn't. As Charles Barkley would say, "turrible".

I busted at the end of the night when I raised an opener with KK, at around $500 effective. He called, then donked the KJ8 flop. For some reason I only called. Turn was Ts, which brought a flush draw. Villain leads again. Now, I suddenly am concerned about AQ. I totally didn't think of it on the flop, as I was focused on the fact that OMG I have a set of Kings! Here, I didn't know what to do. Perhaps I should have shoved. I called hoping to see a free river. The river was a low spade, completing the flush. Villain checked, so I got my free card. But now I lose to a straight or a flush. I quickly shoved, but it was too small, only around $220 into about $660. Villain called with AQ. 

I think my player pool was mostly regs this night. I saw one player use aggression well. Otherwise, I saw the same loose passive (lots of limping) play I see at my $1/2 home game. There was lots of poor play, which meant I fit right in.

How to Fail at Almost Everything and Still Win Big

This is the story of one person’s unlikely success within the context of scores of embarrassing failures.
— Scott Adams

Scott Adams, probably best known as the creator of the comic strip Dilbert, has more failures than successes, yet he is still a big winner at life. Scott's latest book, How to Fail at Almost Everything and Still Win Big, chronicles his system for a good life.  This book is part self-help manual, part autobiography, part history of the Dilbert comic. A fan of any of those things will enjoy this easy, fun read. 

I've always been a fan of the Dilbert comic, but I knew very little about Scott Adams until a couple years ago. when he wrote a very provocative post about end of life care and government interference. It's one of the most amazing things I've ever read, and it put Scott's blog on my radar. Last fall, I noticed Adams was blogging on the presidential election, specifically, he was focused on Trump and predicting Trump to win in a landslide. The posts were prescient and intriguing, and they demonstrated Scott's range outside the world of comics. He regularly added a postscript to his posts, mentioning his book. I'm glad he persuaded me to buy it.

In How to Fail,  Adams sprinkles stories and examples from his life with his advice for how to build systems for success. He gives lots of advice, but the core ideas are as follows:

  • Systems vs. goals. Systems are for winners, goals are for losers
  • You can change how you act and how you think
  • Personal energy is the key to self improvement
  • It's unlikely you'll have any one exceptional skill, but if you stack several skills together, you can win. Every skill you add doubles your chance of success, and some skills are more valuable than others (he gives many good examples, including Persuasion)
  • How to be happy? Basically health and freedom
  • You can increase your chances of being 'lucky'
  • How to conquer shyness, be more outgoing
  • Tips on diet and fitness, via systems
  • Simplicity can produce amazing results

Adams writes in a simple style, and makes it easy for the reader to read this book in short bursts, as the chapters are short to the point. The book contains lots of interesting details about Adams' rise to fame, his many failed ventures, and some personal health struggles, all with doses of his humor. Most of his advice seems reasonable, and if you read other pop social science, you'll recognize a lot of his advice. However, this is not a pop science book. This book reads like a conversation with a friend over coffee. 

A few things might be controversial, but he warns throughout that this is a system that worked for him, not something everyone should try. One small example is that he finds peanuts to be a healthy alternative snack. Some might disagree with the choice of peanuts, but it's not a big deal. His point of making small tweaks to your diet, to provide quick energy boosts without a lot of calories, is worth considering. A bigger idea that might be controversial is his practice of daily affirmations. Science is mixed on this, and conventional science is very skeptical. Adams warns of this, and simply says it has worked for him, even if those successes were simply coincidences. Adams has written a couple other books, with some controversial ideas about religion. His blog posts have also stirred controversy at times. This book, however unconventional, is not controversial. I think most readers will find a few good tips, probably more, they can incorporate into their own lives.

A Teachable Moment - Charity is Complicated

Several weeks ago, I had an interesting conversation at my local Rotary meeting. Several friends and I were enjoying lunch, waiting to hear from one of the Home Depot executives, when the conversation turned to the $1 billion PowerBall lottery. A good friend, we'll call him Steve, picked up on the theme and told the story of his recent encounter with an apparently homeless person. Steve was in rural Georgia hunting with his family. He stopped at a convenience store with two of his young sons to get supplies. On the way out, they saw a man scavenging the nearby dumpster. Steve only had 3 dollars cash left, but he gave it to the man before driving off. A few moments later, Steve realized he had paid for a bag of ice, but did not retrieve it from the freezer outside the store. Steve returned to the store, and poked his head in to tell the cashier what he was doing and he spies the vagrant spending the new cash on lottery tickets. After retrieving the ice, Steve shared the new information with his sons, and told them is was a teachable moment, that you can attempt to help people, but you cannot make good decisions for them. 

I told Steve the vagrant's action seemed rational to me, and one of our friendly arguments ensued. Steve thought the recipient should have used his new funds for a meal or something of value. I think the vagrant did that, in his mind.  Here, I'll try to defend the vagrant, and encourage Steve to  give again in the future, regardless of this incident.

Allow me to back up, and touch on the broad question of sovereignty. Once you make a gift of any kind, you have no ownership over the gift. It's common for givers to try to exert ownership, but those actions are what have created our dysfunctional, ineffective non-profit system. As a libertarian, I believe all competent adults are sovereign, capable of making their own best decisions. If I were in Steve's position, I would hand over the $3, and it wouldn't matter to me how the money was spent. It's none of my business. The recipient is the best person to know how best to spend that money. Consider Milton Friedman: 

There are four ways in which you can spend money. You can spend your own money on yourself. When you do that, why then you really watch out what you’re doing, and you try to get the most for your money. Then you can spend your own money on somebody else. For example, I buy a birthday present for someone. Well, then I’m not so careful about the content of the present, but I’m very careful about the cost. Then, I can spend somebody else’s money on myself. And if I spend somebody else’s money on myself, then I’m sure going to have a good lunch! Finally, I can spend somebody else’s money on somebody else. And if I spend somebody else’s money on somebody else, I’m not concerned about how much it is, and I’m not concerned about what I get. And that’s government.
— Milton Friedman, in a Fox News interview in May 2004

Uncle Milty was focused on the inefficiency of government, but his argument applies to large bureaucracies like charities, and for individual decision making. Incentives matter.  The best way to implement this idea is to give directly, without strings attached. There are a number of legitimate charities set up now to do just this, one of which is called Give Directly. All they do is give small amounts of cash to extremely poor people in the third world. They bypass all the inefficiencies, and simply get capital where it is in low supply. Academic research suggests they are far more effective at reducing poverty than traditional giving. 

Coming back now to the specifics of Steve's gift to the vagrant, Steve likely gave the gift without any strings attached, and would have likely felt good about his action had he never seen the person again. However, once he learned of how the vagrant chose to spend the gift, Steve made a moral judgement, one that changed his view of that gift, and possible future gifts. He even went so far as to try to influence the future gifts his sons might make. The key issue is not Steve's gift, but the moral judgement many make when a poor person spends what little capital they have on a highly speculative venture. I think Steve's view is the conventional one. Lotteries are referred to as a "stupid tax" by many. How can it make sense for the poor to spend their money on lottery tickets (or other gambling for that matter)? Mathematically, it doesn't. The lottery is a losing venture, regardless of the financial status of the player. The difference is the utility. For the vagrant, the low odds of the lottery payout are better than his other available options. That may sound unbelievable but it's often true, according to academic research. There aren't any banking options for him to save the funds. Any cash kept on hand is likely to be lost or stolen. The best options involve spending. While it may seem rational to spend the money on food, the vagrant decided his food options were not superior to the hope, excitement, and small possibility of winning the lottery. 

I'll close this excessive post with an anecdote from my business. I provide high level financial planning to wealthy individuals. A significant part of my job is to advise on charitable planning. In my experience, most people do not think about giving they way I've suggested above. They give with strings attached. When they give money to a college scholarship fund, they want some say in the type of student who will qualify, instead of just finding a needy student and giving them money directly. I've also seen a lot of disappointment when clients have made direct gifts to friends and family. When they give money directly, they are sometimes disappointed with the choices the recipient makes following the gift. In short, my clients have often felt the same disappointment Steve felt, despite giving to folks who were not poor, and not unknown. In my experience, it is very difficult to give something away without being emotionally attached to what happens next.  Charity is complicated.



Who's Your Favorite Female Drummer?

Quick, name a female drummer. Don't google it, just answer.

None? Me either. I can name several male drummers, but no females. I'm sure there are lots of them, and that many are among the best in the world. I just don't know about them.  Most popular musicians, whether part of the named group, or simply supporting a named act, seem mostly male in my experience. It's not just popular music. Google the issue of females in symphony orchestras and you'll see they represent about 25% of the population. It appears that women are underrepresented in the musical industries (as musicians, not singers), yet little is being done about it.

Contrast this with STEM (science, technology, engineering and math). Women are underrepresented in these jobs, and everyone knows about it. There is a national policy to change this outcome (plus many private, and semi-private initiatives). 

I don't have any key insights into why these patterns exist. I'm skeptical of claims of institutional bias, but that's not my point. Assume I'm wrong about that. My question is, why is society going all out to change the female participation in STEM, but not in other careers? Society seems to be upset that STEM fields are dominated by men, but they passively accept that other fields, many fields, are mostly filled by men. On the flip side, the percentage of women in medical industries seemed to go from zero to equal quickly and without major governmental programs. So, what's special about STEM?

The most common answer I've encountered is that society desperately needs more STEM professionals, and growing female participation is one way to achieve that goal. That makes sense, but I don't think it fits our history. Before the effort to get more women in STEM, there were efforts to get more men in STEM. But those efforts were unsuccessful, because there continue to be cries that we are short STEM professionals. Perhaps the STEM industry are just good at ubiquitous marketing. Or perhaps, STEM is a good target for social justice campaigns, where motives count more than results. 

If you know the answer, please share.
