So they are essentially producers of human resources. But I can't agree that their kids will be like their mothers. First, if they are boys, there is no way they will be supported as their mothers were. But even if they are girls, their future is still uncertain as it is mostly defined by their environment and how they are raised up. And the daughters are likely to despise deep inside such way of living ("parasitism")
I sure hope that's just the end of it and it don't end up destroying communities. I don't live in the US but I see people blaming these incentives for the destruction of black families and they do somehow make sense, that community have a high rate of single moms. Also not easy to move out of ghettoes I suppose.
