Well, here everyone gets the same child benefits per child. Everyone gets the same generous amount of child leave. If you're poor you can get different kinds of benefits like for housing, but hardly enough to leave me with less money than someone who can't otherwise afford rent. Yet we see the same tendency here. Lower income families tend to have more children despite earning less in net. So I think you have to at least consider the possibility that it has less to do with the financial hardships, at least in absolute terms of income, than with some correlated factors in your home country. For example, the low income population here are generally less educated. Perhaps people end up more aware of the consequences of having children through education. Maybe there's an underlying factor that leaves people with both a propensity for academic achievement and an inclination towards having less children, like time consuming dedication to an interest or a career. Perhaps higher income parents have higher and more costly standards for their children. I don't know what country you live in that the middle class generally ends up with less disposable money than the lower class through wealth redistribution programs, but it's not the case here or in many other countries where the negative income-children correlation can be observed. I won't comment on darwinism or the idea of Idiocracy as a realistic outcome of any kind of selection process other than to say that it's stupid. If you are able to have children but won't, you have yourself to blame for nature selecting against you, if that's at all an issue to you.
