How would that fix the broken governments, schools, and rampant crime?
The cities I live near seem to have no problem attracting young singles and couples. Young urbanites I've worked with have all moved out when (a) they have kids and realize how bad the schools are, (b) when one of them gets mugged, (c) they get married to a non-urbanite, (d) they want local governance that is at least slightly sane.
It's insane that so many cities will spare no expense to avoid doing things that actually matter, no amount of resources is spared to ensure serious drug addiction, homelessness and crime runs amok.
