We have LBJ and the huge Democrat majority in Congress elected in 1964 to thank for this mess as they guaranteed the outcome with the sweeping Great Society programs. So in a sense, it was "whitey" who did this to them. But that "whitey" was LBJ and the Democrat Party/Liberals and not whites in general.
"I'll have those n*ggers voting Democratic for the next 200 years." ~ Lyndon B. Johnson to two governors on Air Force One
He hated blacks as did all of the Southern Democrats.
