This is a stupid take, frankly. Lots of crime in major American cities would go away if much more affordable housing was available. High cost of living causes poverty and stress, which can lead to drug use and mental illness. It's very obvious that these things are related.
If low cost housing is the silver bullet that solves the whole issue why doesn't the existence of low cost housing elsewhere solve the problem? The one time cost of transport to those locations would be insubstantial and irrelevant.
We tried building solid but low-frills housing developments in major American cities that impoverished people could live in for basically no cost. They became crime-infested hellholes.
