No, they were caused by the Democrats’ decades of welfare and social programs that created “the hood” and a society that sits and does nothing but wait for the gub’ment check to arrive. Democrats, after all, need to keep these folks under their wing in exchange for votes. Hopefully blacks are waking up to this fact.
It goes back 150 years, to the failure of assimilation. When the Civil War ended, there was a massive population with little in common with the mainstream culture at the time. 150 years later, the same situation persists; I guess the closest they came was the 1950s. While oppressive laws still persisted in some areas, the military was desegregated, more families were intact, and education went a lot further despite less money for it.
The DemonRAT “leaders” in these big cities are only concerned on how they can line their pockets. Much of the money comes from the illegal drug industry, which provides them the means to hide their money. There is no effort to fix the unemployment problem because that problem works to drive more people into the underground illegal drug industry. That makes more money for them.
