Problem could be economical. The rich want to get richer and more powerful, the poor and rest of the 99% have issues. Solving a lot of these issues would mean less wealth and power for the rich. So they need to create scapegoats. And racist stereotypes are probably the easiest way to do that. Close second are the people who think differently than [your_group].

helps that the same rich people have lots of influence over what the rest sees, hears and thinks.
