People want suburbia because crime is often lower. Why won't we accept this reality. I don't understand why so called progressives don't just face this issue head on. Increasing incarceration rates makes cities safer. It's true that some small number of people will be jailed. It's also true that more people would move to cities.
And before someone throws out some nonsense politics. I live in the inner city (less than a mile to downtown) in a west coast major city. I can count several neighbors on my block, people who've lived here decades, who are leaving due to crime / rampant drug use.
