That's not easy.

Take public transit, for instance. Arguably, that would be a good thing to change - supply fast, frequent, convenient public transit. But how would you do it?

US cities (with few exceptions) have reached a stable equilibrium where cars are necessary because there's no convenient transit, there's no transit because the city doesn't have the density to make it worthwhile, and it can't have the density because there has to be parking for everybody's cars. How do you change that? You have to change all three pieces at once (plus peoples' attitudes). You almost have to start over with a new city.

If the citizens don't want it, then of course it's game over.

If the citizens do want it, you can just gradually make private car ownership more expensive and less convenient vs public transit.

Anecdotally many anti-public transit opinions from US folks seem to be around having the less well-to-do present in buses, complaints about hygiene and/or safety. So maybe improve the social safety net at the same time, or go full classist and have separate 1st class & 2nd class compartments.

Of course the U.S. has the chicken-and-egg problem, but public transit is my vote if I could wave a magic wand. I am tired of car cities: more pollution, obesity, rage, and sprawl.

I'd say the logical place to start in the US is by finding the streets that have negative cash flow just from maintaining the infrastructure, and start handing those streets back over to the home- and business-owners located on them, in whatever way seems the least politically suicidal. If you live in a cheap SFH on a whole acre,or own storage units, there's no reason you should expect urban-quality roads, water, sewage, and emergency services.

I agree, and it seems like many people share our feelings, which makes sense when you look at how the most desirable cities according to our views are getting more and more expensive. Of course there aren't many of these cities in the US.

The solution I'd love to see is giving these cities more competition. Let's try to revitalize old cities like Baltimore and Cleveland to give people more affordable options. I've heard Pittsburg is having some success with this kind of thing.
