Class and race are the big dividers.
I worked for a company based in Philadelphia, a great city with one of the largest black communities in America. Of course I saw Black, Hispanic and Asian Americans all the time, but not so much where I stayed and not at all in senior management. I was an export salesman, the company hired locals for Russia, Latin America, Australasia and so on but for North America, Europe, Africa, India and the Middle East it was all white guys and one woman.
This unconscious bias is everywhere, not just the States, it just seems more incongruous there given the nature of their population, but truth be told in my thirty odd years working for corporate America and Britain I mostly swam in a sea of fairly well heeled, white, middle class blokes. They made all the decisions coz that's the way it's always been and for many that's the way it's always going to be. It's not overt racism (though some would say otherwise) it's subtler than that, white people like them running everything, it's all they've ever known.
So when that Republican states....
"Many of these folks want to do is change the entire fabric of the United States of America and just make it another multi-nation country."
