It really is up to society if they want to subsidize child rearing. On one hand, we really don't have a dire need for population - reproductive rates right now are sustainable, and we should be trying to disincentivize those from having kids who cannot afford it. They are very expensive and time consuming. On the other hand, people have kids anyway, and then the children suffer when the parents cannot afford them (in either money or time with them, as is the case of most two income households). It isn't a black and white moral situation though, because you don't want to put people in the state of mind that having children can be profitable.
