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.
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.
