In short, the structure of the Welfare System has created more single moms, the destruction of the family unit, the high unemployment rate among black youth, and the high crime rate.  The Welfare System incentivizes all of the negatives.  And once a kid has a criminal record, he's virtually unemployable for the rest of his life, so crime is his only option.

And that's why it's called "The Welfare Trap."  You can't get out of it.
