Stop asking how the poor are going to get to work without cars, and start asking why the rich won't let the poor live close to their jobs.
I heard in Germany they have mixed income neighborhoods on purpose so the poor aren’t excluded from community and services
I don’t know how they accomplish it or what “on purpose” means but we should learn and do better in the US (in my opinion)
Some US neighborhoods work this way, but almost anywhere an interstate plows through there is a big problem. They are dividing lines
