A basic function of societies is caring for the young (and old) and I believe socializing the costs of early rearing of children is beneficial to literally everyone. Right now you may not want to help, but when you're old and decrepit you'll want to be living in a functioning economy run by the children you contributed some money to help grow into contributing members of the economy.
