Are you sure about that? I live in the "west coast" and see plenty of people who seem pretty damn content with their checks they receive from my hard work.
I used to as well. I know there has been tension between the Latino and black communities for some time--not over jobs or money, but POWER. Case in point--as communities went from predominantly white to black in the 1950's and 60's, over the last 10-15 years they've gone from predominantly black to Hispanic, causing a lot of shift in the seats of power in places like Los Angeles.
Entire schools were rioting, and AFAIK, outside the immediate LA area, it went pretty much unreported.
