I'm down with xenophobia but not down with Trump.
All of us WWII baby boomers ('45-'50) probably wondered why the immigration quotas weren't working and that demographics that effected us personally were changing. I have a couple of theories. 1. The US economy was the largest followed by US foreign investments after WWII as the major industrial areas of Europe and Japan were leveled and had to be rebuilt with American loans. The US economic powers that then were, needed a US presence in other countries and didn't want to set an example of seriously blocking immigration regardless that the rate changed demographics. 2. The US southland treating black badly drove them north and having lived being treated criminally and denied decent education were prone to crime ruining major northern cities (I was born in Brooklyn). So, the Vietnam war was truly racist to punish southerners (priding themselves as warriors) and blacks. Meanwhile there were low-incoming housing projects like on Long Islands gold coast (who in their right mind would put projects for poor blacks in the domains of the very, very wealthy old money families?) which I think was to promote a less aggressive prosecution of anti-Vietnam war protesters (Vietnam a racist war). Now you had black housing projects where previously the minorities were black families who served the wealthy and were/are quite nice, and Italian immigrants. The non-project landlords, like the Italians, made it very clear they would house Latino immigrants and fill their minority housing requirements with Latinos. So, the real estate and housing lobbies saw the increased population pressure and rising profits, so did banks.
