This show isn't about how "all white people are racists". Thought I'd get that out there after reading some other reviews and then watching the series. If anything, it's an indictment of capitalism, of how money buys power and power buys policy. Most of the money in the states IS in the hands of white people, and mostly white men in positions of industry - that's not a "take", that's statistics. So a lot of the bad guys are white, because realistically, they would be. There's also a neo-nazi group, so obviously they're racist and are depicted as such.
It's a good show, not perfect but that's OK, it's definitely worth a watch.
