Charles Murray has written about the class structure evolving in the US, where now the elites (top 5%) go to the same few public or mostly private schools, live in the same zip codes, attend the same colleges, shop at the same stores ... and have almost no interaction with the middle and lower class.
Thus you get people who consider skilled blue collar work demeaning, bad, stupid, demonstrated by the push to automate the work on the assumption "no one would want to do that" when it is really "I'd find that boring and dull, we shouldn't have anyone do it". I actually had that discussion at a robotics/automation forum, and I was the only person who had worked in manual labor as a teen / college, engineer in factory as an adult, supported food banks and help for the mentally disabled.
There is also a massive cultural divide between the upper class and middle and lower class, from TV shows they watch to movies they like. This is how rich white Democrats can bash poor whites as stupid, immoral, evil for supporting Trump, not caring that their push for diversity (hey, ethnic food from around the world brought by immigrants makes life better!) leads to loss of cohesion, competition for low skill jobs among the poor, fewer resources in poor schools because bilingual takes money from special education. They just call anyone opposed to more low skill immigration racist, bad, shut up you evil bigot.
The irony of the "privilege" argument based on skin color is that it ignores class, so the daughter at Harvard of two black doctors can say she's oppressed by a kid whose family has never had a college graduate or middle class job, whether from Appalachia or Kansas. Then the upper class PoC can attack whites for not following a strict speech code and values that put them on top and others on bottom, in the name of ancient history, ignoring systemic oppression of the poor today.
I cover some of this, too, in my Hub reviewing the book "Making of a Social Justice Warrior"; the author is a socialist/communist who criticizes SJWs for mixing up classism with racism.
The only racial component is 1/4 of whites are illegitimate while 3/4 of blacks are, but that only started to rise after the 1960s welfare programs. There are still more poor whites than blacks, but they don't matter in today's victimhood hierarchy, and poor blacks don't get much, either, than hash tags and space to riot.
