Alright, I'm the creator of this user account and the one that made it public, and I'm going to claim it back now. Maybe I'm a dumb kid, but I think if any country can maintain a highly diverse population without internal "simmering war", it's the US. The greed of hospitals is not somehow explained by xenophobia. Generations of people born in perverse power structures, doing their best to strengthen and reinforce them, seems much more suitable of an explanation. Genetics will mix and people will evolve. Deal with it.
