A lot of the issues you reasonably want to avoid seem like they could be solved more directly by other means. The argument seems to be, "America is a hell hole, so everyone needs enough money to escape it." There are poor countries where people dont live in fear of eviction and the slums arent full of violence and drugs. Maybe it's too difficult to change culture though, and we should just throw money at the problem.
The fact that it can be done in a poor country is all the more reason that it's a scandal that it is not being done in a rich country.
These poor countries don't have any special techniques or mystical cultural powers. For example, the fact that south Korea has adequate flood defences and the UK does not is not because Korean culture lends them a racial character uniquely cognizant of water management passed down from their ancestors over generations of rice cultivation or whatever... There is absolutely no reason the UK is unable to "throw money" at constructing flood defences (altering planning policy, etc.) if they were to so chose.
The idea is not to "escape the hellhole" but to transform it in to "not a hellhole", through the direct, rational application of readily available, and completely straight-forward policy mechanisms.
But maybe it's too difficult to use political policy as a tool to achieve desired outcomes and we should blame the victims, turning it in to a nebulous cultural or moral failing and then wait around for the culture to just spontaneously change itself, eh :)
