American Indians / European half breeds. There are some countries that have black people, like Brazil (Portugal emigration). Spain and Italy are the countries that controlled Argentina / Uruguay / Chile (?). Im talking about 500 years ago.
I think this is a chicken-egg thing. I dont know what goes on in the US, but in Argentina, the government isnt helping any of these people. they said they do, but they dont. Governments always take advantage of the poor. In Argentina poor people have kids just so they can collect some money for free, and many dont want to get a job, because if they get it, the government is gonna stop giving them money, they rather have $100 and barely eat, than have $1000 and work. But like I said, thats a consequence of poverty, they are not born like that (thats racism).
Its discrimination to the poor, and most poor are not white. So it gets mix up.
