I'm sure it does say something, but implying have-nots are in their situation because of a lack of education is rather unenlightened. The number one predictor of salary, is the salary of the parents. I would rather put forward that those with subsistence lifestyles sacrifice proportionately less wealth to have many children. So it perhaps is rational to keep children in those cultures and develop morals that encourage this. In more wealthy societies the cost per child is quite high with advanced education, and a lower likelihood that each child provides free labor to the family, so keeping a child is less rational.
