"The family structure breakdown among the poor is directly, painfully correlated to the high incarceration rate. Absent fathers are absent because they're in jail, or expect they will be sooner or later, or because they're ashamed because they are unable to provide for their children."

The Moynihan report decrying the break down of black families was released in 1965, before the drug war, at a time when incarceration per crime committed was approaching all-time lows.

The incarceration rates in America bottomed out around 1973. At that time, about 63% of black and poor persons lived in a single-female headed household. By 1978, with incarceration rates still within their historical range, the rate was nearly 70% (source Losing Ground by Charles Murray). Family structure breakdown came first, it was not caused by incarceration. It is wishful thinking to believe that if all these men were not locked up they would be upstanding and faithful fathers, the problems go far beyond that.

It sounds like you have a bone to pick with black men. Try reading some recent data: http://www.nytimes.com/interactive/2015/04/20/upshot/missing...

It's a structural issue and is very hard to fix. Men, everywhere, do what is needed to get sex. If women and the institutions of society do not require a commitment from the man in order to have children, then men will not give such a commitment. Why would they? But traditionally it is the father who restricts access to his daughter, or trains his daughter not to open up so easily. So fatherlessness begets fatherlessness.

If you think fathers control the sexuality of their teenage daughters, you've obviously never raised one!

They used to have a lot more control, now barely any. Hence the rising illegitimacy rates across the board, for all races.

Shared environment still matters a lot. One father has a limited impact on his own daughter. But if the community has lots of fathers, all telling their daughters the same thing, and so your daughter has friends who all view it as low-status to have children at 16, then she will be a lot more likely to wait on having kids until marriage.
