Culture War Roundup for the week of March 27, 2023

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

YIMBY sentiment on this forum has (I think) been mostly focused on increasing the density of existing residential zones. However, it may be worth noting that there is an alternative: converting existing agricultural or unused land to low-density residential use (i. e., continuing to "sprawl"). In this article, a former employee of the libertarian Cato Institute accuses that organization of focusing exclusively on high-density housing, and of smearing as racist people who are not interested in long-term high-density living and clamor for more single-family houses. (In his view, upzoning imposed from the top down is not libertarian, because the existing owners have a sort of property right in the zoning of their neighborhood as a substitute for deed restrictions that could or should have been used instead of zoning codes.)

Wouldn't that just worsen social car dependency?

I don't think he sees "car dependency" as a problem.

Every city in America is a 15-minute city if you take automobiles into account. Thanks to automobiles, the typical U.S. urban resident lives within 15 minutes of more than 100,000 jobs, several different supermarkets that compete hard for their business, one or two shopping malls, parks and other recreation facilities, a variety of health care facilities, friends and relatives, and many other potential destinations and activities. Even the densest cities in the world can’t provide that kind of variety and opportunity within 15 minutes on foot.

An older article:

According to the 2000 census, Los Angeles is the densest urban area in the United States, and 89.5 percent of Los Angeles commuters usually drive to work. Just to the south, San Diego is only half as dense as L.A., and 90.9 percent of its commuters drive to work. Atlanta is only half as dense as San Diego, and 93.5 percent of its commuters drive to work. And Lompoc California is about half as dense as Atlanta, and 94.4 percent of its commuters drive to work. So doubling density might get a little more than 1 percent of commuters out of their cars. That’s not much.

Low densities, large parking lots, and other indicators of sprawl are effects of automotive technology. They don’t make people auto dependent; they enable people to be auto liberated. Density and various design features planners want to impose will have, at best, marginal effects on the amount of driving people do.

Thanks in part to cars, the average American takes only about three or four thousand steps per day and looks like a WALL-E character. I suppose that the standard libertarian perspective on this would be that the revealed preference of Americans is to avoid physical movement and that governments should try to accommodate that preference, but it's surely not how I'd like my city to approach things.

That’a certainly one of the drawbacks, but it’s also worth considering this in both historical and global contexts.

From historical perspective, Americans have been driving a lot for many decades now, but obesity rates have only shot through the roof relatively recently. This means that other factors contributing to obesity might have much bigger impact than driving.

Second, it is worth observing that European countries, which allegedly are more walkable, and where people drive less, are rather quickly catching up to obesity rates of Americans. The upward trend is clear and is not looking like it is plateauing in most countries. See eg. Germany or UK.

What explains Europe? Is it the food? It can't be smoking or leaded gasoline that was keeping the obesity down over there (unless they regulated those things later than us).

This is not Europe, this is everywhere. As for explanation, I like how Charles Murray's wife has put it:

We decide exactly what we're hungry for and make it for dinner, every day, from a far longer list of favorites than people had 60 years ago. The perfect way to generate weight gain. And we are not alone.

Even if you refrain from eating snacks or sweets (and these also have been extremely optimized for palatability, with many different local maximums to choose from), we are no longer constrained by difficulty of obtaining ingredients, or cost for normal breakfast/lunch/dinner sort of food. Everything is available close by (or can be ordered online), and everything is very cheap relative to our incomes.

...That does make sense. We're more globalized, and we're also the opposite of starving, in general.
