We’ve always had minorities in liberal cities and in conservative ones too.
America has been undergoing a deep change, starting in the early 60’s. I don’t really understand it, but I think a central part of the explanation is the fact that for almost every living American, all they have known is being citizens of the world’s most militarily powerful (by far, in comparison with all others) , prosperous country … not threatened on our borders … dominating the international institutions… with growing comfort and prosperity for anyone who can get a college education (and for many others as well, at first).
So we’ve grown a generation of self-centered weaklings, whose personal self-gratification is their most important goal. They can’t stand the idea of hearing any idea that might make them feel ‘unsafe’. They have contempt for their own working class, and for their country’s history.
This situation affects different social groups in different ways.
For Blacks it was the disintegration of the Black family, plus the loss of unskilled and semi-skilled jobs. See the Black leftist sociologist William Julius Wilson’s book, When Work Disappears. I agree with his analysis … combine that with our drug laws, which make selling dope an easy and well-paying job … but one that you can only do if you’re a member of an armed gang … and you can see the problem. (Yes, our free market folks will say they can always get a job flipping burgers for one-tenth the pay. Ha ha.)
For white middle class kids it was different. Middle class liberal whites don’t understand why, further down the social/economic scale, the whites ‘cling to their religion’, and are so dogmatic about morality.
What they don’t understand is that the same sort of behavior that middle class college kids go through – experimenting with drugs, easy sex – can be devastating to young people in small towns … teen age pregnancy, meths instead of marijuana.
Similar to the Blacks, in fact, as we are begining to see in places like Appalachia. [See Charles Murray’s Coming Apart. https://en.wikipedia.org/wiki/Coming_Apart_(book) ].
I’ll quote a bit from the Wiki summary of that book: Charles Murray describes what he sees as the economic divide and moral bifurcation of white Americans that has occurred since 1960. Murray describes diverging trends between poor and upper middle class white Americans in the half century after the death of John F. Kennedy. He focuses on white Americans to argue that economic decline in that period was not experienced solely by minorities, whom he brings into his argument in the last few chapters of the book. He argues that class strain has cleaved white Americans into two distinct, highly segregated strata: "an upper class, defined by educational attainment, and a new lower class, characterized by the lack of it. Murray also posits that the new [white] ‘lower class’ is less industrious, less likely to marry and raise children in a two-parent household, and more politically and socially disengaged.

But today’s liberals, pushed to the left by more conscious, radical ‘progressives’, and completely consumed by white guilt, are letting the citeis they control spiral downwards into Third World hellholes. The oppose effective policing, they oppose effective educational policies. So the Black kids in the cities they control have no hope.
