The reason is true but eventually the black ppl of today are going to have to stop using the generations of oppression to excuse the present.
Cause & Effect is about as basic a concept can get.
We have years upon years upon years, of being taught hatred of eachother, division, exclusion on how to accumulate funds, history of our culture, lack of family structure, lack of knowledge of health... and yet people think that's this is just a matter of black people not doing enough.
The same people who controlled and oppressed 50-100 years ago, control & oppress at an even higher level now and have more control then they ever did. So the cause is still exactly the same yet the effect is expected to change? it doesn't work like that.
