On a recent flight I watched (but did not listen to) the live action version of Cinderella. Historians tell us that princes and kings back in the old days were not typically set far apart from ordinary nobility and they tended to affect a “first among equals” manner even when they were. In the movie, however, when the prince and Cinderalla dance everyone else at the ball (presumably all noble) stands in a circle to watch. Children learn from watching this that some people are vastly more important than others, the exact opposite of what their K-12 teachers are supposedly telling them.

So here’s a question for readers: Why is this message popular with children? We know why the chain of being was popular with rulers, but I don’t think anyone is explicitly telling those who make children’s movies to emphasize this concept.

In February I posted a note about TransAsia 235, the turboprop that crashed in Taiwan. I suggested that, in the event of an engine failure, the pilots didn’t have to do much of anything other than fly the airplane. The official factual report is now available.

The engine failed about one minute after take-off (see page 12). Automated systems then shut off bleed air from the good engine, so as to maximize its available power (bleed air from the compressor is used to run pressurization and de-icing), temporarily relaxed a power limit to the good engine (“uptrim”), and, more important, feathered the prop on the failed engine so as to reduce drag. At this point all the pilots had to do was leave the throttles pushed full forward and fly. The pilot flying (PF), however, pulled back the throttle on the good engine about five seconds after the bad engine failed, ignoring the PM’s (pilot monitoring) suggestion to “wait a second cross check.” (A third pilot, an “observer” (OBS), sat behind the PF/PM in the front seats.) With no power on one side and limited power on the other side the airplane crashed about two minutes later.

Not a great day for John Henry…

[Illustrating the human bias towards action, the press coverage of this latest discovery has failed to mention “doing nothing” as a superior alternative to what the pilots actually did. A non-pilot reader would be left with the impression that the crew should have moved at least some levers but unfortunately moved the wrong one when in reality a far better course of action would have been to touch nothing. (Corollary to the First Principle of Flying Jets: “If a switch has dust on it, don’t touch it.”)]

• part of my email report on flying a Beriev Be-103: “pulling an engine back to zero thrust is an experience you won’t soon forget. The yaw isn’t that dramatic because the engines are inboard. What is dramatic is the sink rate at blue line. We were at 3000′ on a cold day and couldn’t hold altitude. It turned out that we’d [we = TWA captain demo pilot plus newbie (me)] left the cowl flaps [air inlets to cool the engines at high power settings] open and that was enough to rob us of the advertised 3000′ service ceiling. A piston twin is a pretty bad aircraft and an underpowered piston twin is scary bad. The ship has 210 HP per side. It probably should have at least 250 or, better yet, a single 450 HP turbine.”

What percentage of U.S. GDP is simply moral hazard? The U.S. is one of the world’s most heavily insured countries and Americans are not notable for considering the welfare of their insurers.

Let’s consider health insurance, the purchase of which is now required by law. Would people be discouraged from risky behavior if they thought that they’d have to pay medical costs likely to occur as a result? Can any non-emergency trip to a U.S. hospital be considered moral hazard? If an American didn’t have insurance, presumably he or she would fly to Europe, Mexico, Israel, or India to have a procedure rather than pay 5X the world market rate.

Taxpayer-subsidized flood insurance is another obvious example. A lot of Americans have built and rebuilt fancy houses near the beach or rivers because they don’t have to pay the true cost of cleaning up after floods.

I thought about this other day because of a condo that I own in Cambridge. The trustees are the owners of the four units and also manage the building (rather than contracting with a property management firm to do it professionally). The top of the building is a 125-year-old slate roof that I wrote about in 2013. The trustees with units on lower floors voted against redoing the roof (cost of $25,000 to $30,000) on the grounds that it wasn’t leaking into their units, but only into the top floor unit, and also because the insurance company had always been there to write checks for repeated damage (minus a deductible each time). The winter of 2014-2015 resulted in ice dams on the roof, however, which sent water down the side walls into units on lower floors. The insurance company estimated that it will cost $100,000 to repair and they are getting ready to write a $76,000 check (the full cost minus some depreciation for damage to areas that hadn’t been painted for a while). In a world without insurance the roof probably would have been fixed a long time ago. In a world with an insurance company cheerfully paying out, a large percentage of GDP will be repairing damage caused by moral hazard.

What do readers think? Is this now a significant percentage of U.S. GDP. Given that health care is 18 percent of GDP it seems as though it could be.

“A World Without Work” is an Atlantic story about what the U.S. might look like after robots and smarter software take over a lot of jobs within the U.S. The author says that the declining labor force participation rate in the U.S. (from 66 percent to 63 percent since 2009) hasn’t been the boon to American happiness that we might have expected: “By and large, the jobless don’t spend their downtime socializing with friends or taking up new hobbies. Instead, they watch TV or sleep. … The unemployed theoretically have the most time to socialize, and yet studies have shown that they feel the most social isolation; it is surprisingly hard to replace the camaraderie of the water cooler.”

This Wall Street Journal article shows that Puerto Rico is about 20 years ahead of the rest of the U.S. The federal minimum wage of $7.25 per hour is 77% of the median wage (comparable to a $13 per hour minimum wage in May 2014 (BLS data showing median hourly wage of $17.09 nationwide)). In other words, it is illegal for companies to hire a large percentage of Puerto Ricans at what would be a market-clearing wage for their particular skills. The result is that labor force participation in Puerto Rico is 43 percent, which means a much higher percentage of the population needs to find something to do every day other than work.

There seems to be a political consensus in the U.S. around raising minimum wage to $12-15/hour. If we assume that Americans as a whole will respond to economic incentives in the same way as those who live in Puerto Rico, presumably the 50 states in 10 years will look like Puerto Rico today (or sooner if the technological revolution forecast by the futurists turns into reality). This makes Puerto Rico a potentially useful laboratory for figuring out how to build a society that is satisfying for citizens when the majority of able-bodied working-age citizens do not have jobs. On some measures, Puerto Rico has already solved the problem of how to build a good society without work. This Orlando Sentinel article notes that Puerto Rico topped a worldwide happiness survey back in 2005. A lot of the boost seems to come from extended family living nearby. The mainland U.S. could be naturally trending in the Puerto Rican direction. As traditional colleges become unaffordable fewer young people will move away from home in order to go to college. As a smaller percentage of Americans work, a smaller percentage will move away from their birthplace in order to work. We could spend more of our tax dollars on festivals and social gatherings (every town every three days) and less on health care (if we cut the percentage of GDP spent on health care to something more like what other developed nations spend we could easily fund all-day, every-day parties; see my health care reform piece for other alternatives). We have 50 million people getting food stamps. What if, for at least one meal per day, those 50 million people were invited to come to a social meal? The same deal with SSDI. We could offer enhanced SSDI benefits for those who move to an “SSDI party village” where at least half of the neighbors are also on SSDI. Then there would be more opportunity for socializing during the middle of the day when 43-63 percent of working-age Americans were at work.

What ideas do readers have? How should society be organized if only a minority of working-age Americans are working? What can we test out in Puerto Rico?

Whatever Greece has been doing economically hasn’t worked out that well, apparently. It seems irrational to say that “What we organized in the past few decades led to insolvency, but we’re much smarter and wiser and would never do that again.”

Maybe Ecuador is the model for Greece. They noted their failures in managing their own currency (the sucre) and voluntarily gave up this government function in 2000, adopting the U.S. dollar as the official currency.

Analogously, the Greeks could recognize that they aren’t capable of drafting and passing laws that lead to a sustainable economy and import another country’s laws and regulations in a big package that nobody can open or tweak. Which country’s laws should they pick?

The CIA Factbook shows that the world’s most successful country, aside from oil-rich Qatar or a few tiny financial services havens, is Singapore. Singapore has a per-capita GDP that is 50 percent higher than the U.S.

Singapore is similarly situated to Greece in many ways. The population is within a factor of 2. Both countries are small relative to neighbors and trading partners. Both countries have military challenges in dealing with much larger potential foes (Turkey for Greece; Malaysia and Indonesia for Singapore; Singapore currently spends a larger percentage of GDP on military than does Greece (World Bank)).

Greeks could strip their politicians of law-making power and say that their courts and police were responsible for applying the laws and regulations of Singapore, however those laws and regulations evolve.

An awesome idea from Spain: hybrid airplane powerplant. Airplanes need about 65 percent power for a reasonable cruise. Airplanes can certainly fly on 35 percent power. Thus having an electric motor that can be used for a boost on take-off and as a backup in case the reciprocating contraption comes apart comes with potential weight savings as well as some potential safety improvements (though not too many accidents are caused by power failure).

With typical regulatory certification challenges this might be ready in 10 years!

“Airlines Under Justice Dept. Investigation Over Possible Collusion” is a New York Times article about the airline industry that the antitrust watchdogs in D.C. allowed to form:

roughly 80 percent of the nation’s air traffic is concentrated among four airlines — American, United Airlines, Delta Air Lines and Southwest Airlines.

Now it seems that the same government that allowed this kind of concentration is investigating the oligopoly for obstructing competition… What did they actually expect to happen?

Facebook friends say that the existence of American citizens who object to President Obama’s policies and proposals is proof that Americans are racist. Partly this is due to the number of people who oppose Obama’s plans and partly this is due to the perceived vehemence of the opposition. Suppose that Hillary Clinton wins the next election, as I would expect. There will presumably be quite a few people who oppose many of her proposals simply because most things that the government does make one group richer while making another group poorer. The same friends will presumably then say that this shows how Americans, who elected a female president, are even more sexist than before.

Could this continue if every future president is black and/or female? The Americans who select members of these groups as their leader will be considered ever more racist and sexist?

Burning Man can be a challenging and uncomfortable place to visit. It turns out that the best way to attend is to work for or be friends with the federal government. For 2015 the Bureau of Land Management is requiring the Burning Man organization to building a $1 million VIP compound (USA Today) with “butter and margarine” (what about the government’s war on transfats?), 24-hour ice cream access, “a variety of dessert served with each dinner,” Chobani yogurt, etc. (Reno Gazette-Journal). They need washers and dryers because, apparently, packing a whole week of clothing is not something that VIPs can do (nor can they take their taxpayer-funded vehicles to the laundromat in nearby Gerlach, Nevada).

The state government doesn’t want to be left out. They’ve passed a law that takes effect in October 2015 to collect a 9 percent tax on festivals such as Burning Man (Forbes). The state, which doesn’t impose an income tax on its own individual or corporate citizens, thus manages to shift even more of the tax burden to visitors. (The state’s tax burden is already pretty low, 8% of income compared to a national average of 9.8% according to the Tax Foundation.) They’ll soon have a $5 billion Tesla battery factory in the Reno area. Perhaps this will become a tourist destination in its own right, leading to more tax revenues from hotel and restaurant purchases by visitors (and a state tax on factory tours?).

(Another peculiarity of Nevada is that they cap child support at a tax-free $13,000 per year (Real World Divorce). That’s double the limit in Germany, and still represents a profit over what typical American couples spend on their children, but Nevada is right next to California, which offers unlimited child support profits by formula to custody victors. If a VIP from Washington, D.C. (unlimited child support by judicial discretion) comes to the proposed “camp uber douche” and invites a young lady from California to come sample the salad bar, four types of milk, seven kinds of juice, etc., there is potential for litigation in three states regarding venue, with millions of tax-free dollars riding on the outcome.)

We’ve endured five years of hearing about Greece, whose population is about the same as the Chicago metropolitan area. Self-appointed experts have said that the exit of Greece would show the failure of the euro concept. Wikipedia, however, shows that there are 19 countries in the monetary union. One failure out of 19 over a 16-year period could also be characterized as “success,” no?
