FTFY, but fully agree.

In urbanized areas (where most people live), we have hit the capacity of the automobile transportation infrastructure. This causes a cascade of real estate prices in urban cores, making the vast majority of these areas unaffordable for normal folks. This is leading to myriad crises, like a massive teacher shortage in California, simply because lower-income people cannot build normal/desirable lives for themselves.

The issue is that automobile-centric infrastructure makes this cascade inevitable in areas where cities grow to the point of infrastructure failure, but the cost of maintaining the infrastructure creates financial problems in areas that do not grow to this point.

None of this would be an issue if jobs were not clustered in big cities, but they are.
