You continue to show how race reductionism works. Whites were not redlined out--the poor ones continued to live in poor neighborhoods. Some of those poor neighborhoods were predominantly black. Some where predominantly white. Segregation was real, but so was capitalism, no matter how hard you try to erase it. What kinds of loans do you think poor white people got in Appalachia?
Yes, richer black people had fewer options than richer white ones, but they still lived better lives than poorer white people. That's why class matters most under capitalism.
What gets called white flight was actually middle-class flight, as shown by the way it continued after segregation was illegal.
If "white privilege" matters today, why have the racial proportions of black and white poverty stayed the same since King's day? If one group had privilege, its percentage should have decreased by now, yet the ratio is still two poor whites for every poor black.
