While I was writing my essay on the chess ratings formula, I recalled enjoying the occasional chess game, and joined Chess.com, an intern chess site with many features. In one month I have played 12 games against humans and 5 or so against the computer. It’s fun, and Chess.com gives me a rating of 1323. It’s my first rating, and though it’s probably only accurate to ±150, I find it’s nice to have some sense of where you are in the chess world. But the most fun part, I find, are the chess puzzles; see some below. At first I found them impossible, but after playing for a bit, the ideas began to resolve, and I began to solve some. There’re not impossible, just difficult, and they only take a couple of minutes each. If you guess my name, you could win a match.

Rents in New York and San Francisco are far less expensive than before the pandemic. It’s been a boon for the suburbs, the south and the midwest, one that’s likely to continue unless Biden steps in. Before the pandemic, rent in San Francisco for a one bedroom apartment averaged over $3700 per month. New York rent was similar. People paid it because these cities offered robust business and entertainment, the best restaurants and bars, the best salons and clubs, the best music, museums, universities, and theater. New York was Wall Street, Madison Avenue and Broadway; San Francisco was Silicon valley and Hollywood. These cities were the place to be, and then the pandemic hit.
Post COVID-19, the benefits of big city life are gone, and replaced by negatives. The great restaurants are mostly gone; the museums, theaters, and salons, shut along with Hollywood. Wall Street and Madison Ave have gone on-line, as have the universities. If you can work and study from anywhere, why do it from an expensive hotbed of Corona.
People of means left the big cities with the first lockdowns. Wall Street moved on line, with offices in New Jersey, and many followed, along with college students, and hotel and restaurant workers. New York’s unemployment rate increased from 4-5% to over 9.5% today, among the highest rates in the nation, 9.5%. It would be higher if not for the departures. Crime spiked; the murder rate doubled. To keep people from leaving, landlords have lowered rents and many will now forgive a month or two of rent to keep apartments full with some rent coming in and an illusion of exclusivity. This is good for tenants, but tough on landlords.
Detroit rent history, 2014 to January 2021. Rents fell a lot on election day, maybe because of Biden, or because we think the pandemic is over.
As things stand, the suburbs and smaller cities are the beneficiaries of the exodus. Among the cities benefiting the most are cities in the south and mid-west: states that are more open and are relatively low cost: Phoenix, Oakland, Cleveland, St. Petersburg, and even Detroit. Detroit’s rents were already moving up as auto manufacturing returned from Mexico, see chart. Between early 2017 and October 2020, they went from $500/month to $1250/month for a 1 bedroom apartment, according to Zumper. Detroit rents fell after election day, but are still up 20% on the year. The influx of wealthier working folk to Detroit is welcome to some, unwelcome to tenants who find their rents are raised. I think it’s is a sign of a healthy economy that people follow life-quality, and that rents follow people. Our landlords are happy, but there are a lot of Detroit renters who are not
Joe Biden has promised to step in to make things right for everyone. He promised to have the government pay people’s rent so they don’t get evicted. I presume that means paying about double to people in NY and SF as to those in Detroit. He claims he will shutter smokestack industries too, and create the good jobs of the future in computers and high tech. It’s a nice claim. I suspect it’s a bailout of big city landlords, but what would I know. I suspect that the US would be better off if Joe just sat back and let New York rents fall, while allowing Detroit to gentrify. Detroiters need not worry about rents getting too pricy here. We’ve1500 shootings per year, that 15 times more than NYC, per capita. Unless that ratio changes, Detroit will continue to be the lower rent city.
There are two remarkable things about shootings in Detroit. One is how many there are. About 1500 Detroiters last year, about 0.2% of the city’s population. The other remarkable tidbit is that only about 1/5 of them died. More specifically, there were 1173 non fatal shootings. There were also 327 criminal homicides, but many shooting deaths in Detroit are non-criminal, as in self-defense, or police interventions, and there are also many criminal homicides that are done with knives or poison. Put this together and it seems that only about 1/5 or those shot, perhaps 327 out of 1500 total. The headline from June 21, 2020 reads: 1 fatal, 11 non-fatal shootings in Detroit overnight. You almost feel like getting these guys marksmanship lessons, but there seems to be more at play.
Even in photography, a fair percentage of shooters miss simple head shots.
The number of shootings are way up this year, and drugs – alcohol is to blame, here and in other cities. People have lost their jobs to COVID and globalization, more in Detroit than in most cities, but the government has offered checks that are used for alcohol and drugs. Most Detroit shootings begin as arguments that turn violent. There is also some gang shooting, enhanced by a bout of prison releases, because of COVID.
Drugs and alcohol help explain the low death rate. It’s hard to shoot straight when you’re drunk or stoned, and hard even if you’re not, as Alexander Hamilton found. In Detroit, many of these hit were hit in non-vital areas (I tell folks to avoid those areas :). But another part of the low death rate is lower caliber bullets. Military caliber bullets were in short supply this year, and as best as I was able to tell, a fair number of shootings were with 22 and 25 instead of the military cartridges, 9mm and bigger that were popular years ago. A 9mm cartridge is shown as the center picture below, between a 22lr and a 45. Big bullets make for big holes and high death rates.
Per capita, the Detroit shooting rate is about 15 times that of New York City. New York saw roughly the same number of shootings as Detroit, 1,531 in a city 15 times bigger, and 462 criminal homicides The cause does not appear economic. but social. When Detroit’s unemployment rate fell, the murder rate did not. Thanks to COVID, Detroit’s unemployment rate is lower than New York’s. My only thought is that the culture is the difference, that the culture in New York is such that arguments do not turn violent as regularly.
Size comparison; 22, 9mm, 45. Big bullets leave big holes.
Stricter gun laws will not help, I think. Michigan’s gun laws make it hard to own pistols with barrels less than 16″ long. The net result is that most crime in the city is done with illegal guns. In general, countries with strict gun laws have more violent crime, not less. I would like to encourage private citizens to choose smaller bullets for self defense though, 22 or 32, and not military grade, 9mm. As a private citizen, you have to bring in the criminal, or storm a building. Your only goal is to get the criminal to stop without harming yourself. A 22 will get the criminal to stop. It will killl too, just less often. A 22 caliber bullet killed Bobby Kennedy, and Reagan was nearly killed with one. A small caliber bullet is less likely to kill you in an accident, or to kill people standing behind the target. This year, some 11 police forces came to a consensus report on use of the minimum of force necessary; read it here. For a private citizen, that’s a 22. Besides, speaking from my own limited experience, I find it easier to aim a small bullet.
Part of the mandate to the 2020 election was to join with Europe and the rest of the western world in agreeing to stop the use of coal. It’s a low cost way to generate energy. Of course we still like to buy things, and we’ve largely turned to China, a country that still burns coal, and thus makes things cheap. The net result of this shift to Chinese goods is that China keeps building coal-fired plants while we shut ours. As it happens, China is worse than the US in terms of CO2 per output, but at least when China pollutes, we don’t see the smoke directly, and we don’t see their new coal plants at all. So we feel better buying things from China than from the US. Besides, slave labor is cheap.
From th eEconomist, December 2020.
Buying Chinese goods is good for the importers, and for the non-manufacturing consumer, at least in the short term. It has the effect of exporting jobs though, and eventually we have to support the displaced workers. It also means we don’t keep up our manufacturing technology. Long term, that affects innovation, and that starts to displace other industries. Antibiotic production has already left the US and along with it semiconductors. Still, we feel good about it since the Chinese don’t let us see the slave labor camps. We do get to see the haze of the pollution.
The Chinese expect this pattern to continue. China is building new coal-fired plants at a furious rate. Presently China has most of the world’s coal-fired power plants. Mostly these are only 4 to 12 years old, far younger than our forty year old plants China plans to build more, and keeps encouraging us to shut down ours. Even 10 years ago, China lead the world in CO2 output. And their fraction of the CO2 keeps climbing.
China is popular with the press. In part, I expect, that’s because they pay the international experts. lAlso, writers and editors are consumers industrial products, but not manufacturers. Consumers benefit from slave labor, or maybe not, but displaced American workers certainly suffer. Also, of course, the news requires pictures and personal stories to keep viewer interest. If you can’t get pictures of young protesters, like Grey Thunberg, you can get an interesting story. Our Chinese pollution is out of sight, and not in the press.
