...They collapsed a long time ago, thanks for nothing. The New BS GOP gave the nonrich pneumonia, and the blacks died...
Oh, horseshit... your feral under-performers, infecting inner-city shit-holes, have merely gotten better at killing each other...
The collapse started with White Flight of the 1930s-1960s, when your under-performers moved North and started pushing down property values...
People flushed their equity in city neighborhoods while they still could, and bailed for the far more civilized suburbs...
Leaving your under-performers to rot for a half-century or more...
And, predictably, being the non-starters and under-performers that so many are, they did just that... rot...
The only difference between now and then is that recent inner-city shit-hole Kill Stats have made the rot smell even worse...
But the rot has been there all the while... hell, vast numbers of them brought the rot with them, and never shook it off... them OR their descendants...
As evidenced by Chicago, Detroit and several other 'beneficiaries' of The Great MIgration.
Hope that helps - restating the obvious in Real World terms, rather than LibTard Double-Speak.
