> actually the U.S. being rich is one reason air quality is improving and better than Europe

Is it that, or that that there is a lot of USA?

Dilution works very well, until it doesn’t.

Not at all - cities are worse in Europe than in the US. European policy pushed diesel cars for a long time, and Europe burns a lot more biomass for heating than the US does. Both of those are localized - it's particulates, especially during winter, that are much worse.

In European cities less people drive.

And yet they have worse air quality...
