When they're not emotionally involved with the children, they tend to do things like keep money under the mattress. It gets hidden and nobody benefits from that. Neither goal will be achieved until both goals are achieved. When they get to a certain place in the workplace, mothers are torn. You can only take that so far without having neglected children or overstressed, saturated mothers.
Life becomes too difficult for both the mother and the child.
So you have to have father involvement. That's level one. There's an important reason for that, which should not lead us to conclude that men are inherently better fathers than women are mothers. The single father has, on average, more income, more education, more motivation. Single fathers today are a little bit like a female doctor in the 1950s.
