And that, right there, is a great example of how we still have racism in America. Not the (im)moral view of one race being better than another, but the sociological definition of a system that favors one race. In this case, our education and economic systems tend to keep poor people poor and rich people rich. Since historically lots of non-white people have had to start from nothing, especially black people in the days around slavery, it's been mostly white people who have been able to accumulate wealth over generations. And wealth, as you've said, is tied to political power so the politicians make sure the system favors peoples with the moneys.
