I’m not sure that I agree… a family is a lot more than a source of economic support. No amount of less hostile world can substitute for the social, cultural, educational or psychological functions of a family, and becoming a self-supporting adult has a lot to do with mental well-being (in addition to the economic aspects).

Maybe if there were less economic pressure overall there would be more functional families and ultimately fewer children in the foster care system… but that’s really just conjecture and I’m not sure how you’d go about trying to support such an argument with research.

I’m also curious how you define “hostile” and “normal humans” in this context.
