I wouldn't say that's entirely true, at least for spine of your points. There are some walkable cities but mostly every city was built long ago that now it's mainly just suburban expansion. It happens all over the country. Cookie cutter communities of single family homes spread out over miles and miles. I live in one myself. There's no need for public transportation since they built homes before building the transportation system. And that's if the place can even sustain a public transportation system. Some cities like NYC and Chicago have great public transport. I know others do too but I can't speak on them. But some cities don't have the infrastructure or capabilities to have better public transportation. Especially with public transportation being mostly in the inner city with more of a population and not the outer parts. Can't really build a train or monorail going into the suburbs with no land to build on, and a possible lack of users with everyone owning cars due to the huge distance between places. White countries like those in Europe have great public transportation and a lot of them are walkable. I know they got the trains connecting practically every country in Europe. But that was cuz those systems were built many years ago and it's easier back then before cities started to grow. And the countries are smaller and able to easily manage their systems. The train system here could be improved but how much use would it actually get? I know here in Florida they have the brightline train, which is expected to extend from south Florida to central Florida, but you still likely need a car or to rely on uber and lyft when you get up there. Same with other cities. They have the amtrak system as well. But are they even that popular or worth it? Looking at their map for example, you can go from Chicago to LA. But is it worth the time wasted in travel and cost? People have gotten used to not having good public transportation in many cities across America. I don't think much can be done to improve the system no matter if it's whites or any other group of people in charge.
