Everyone does have the ability to pull themselves up. We have one of the widest social safety nets in the world. Saying anybody has to commit violent crime just to stay alive in this country is a lie.
Let me be perfectly clear: racism in this country leading back to slavery absolutely led to the cause and effect of where we are now. It would be complete denial to say otherwise.
Two things:
1) There are aspects of black communities that have gotten worse since Jim Crow. Single motherhood rate, violent crime rate, and high school drop out rate to name just a few. There is a culture problem in poor communities that isn't the result of some implicit racist edict from the government.
2) It isn't that the government SHOULDN'T fix the problems black people have, it's that it CAN'T. All the government is doing is creating an entire class of people that are completely reliant on the government. That isn't going to cut it.
If we had as much national enthusiasm about people in black communities taking personal responsibility for their lives as we do about fighting imaginary injustice, I'm positive problems could improve rather quickly.
