[Troubleshooter]

This is a complex problem. You can look at racism, labelling theory, welfare, affirmative action, etc. as aspects that contribute to the perpetuation of the apparent inability of blacks to better their position in society.

But ultimately they are all only factors that contribute to a tendency to decide whether or not to better their positions. The child of a working mother is going to have a better chance at betterment. The child of the working mother's child is going to stand a good chance at betterment if their parent was successful as well. It's a feedback loop of sorts, but until more blacks are willing to fight the factors and start the cycle things are only going to get worse as educational levels decline and racial ratios increase.
