You have done a good analysis except they are not able to feed children. Govt. give them lot of funds to have kids but they don't want responsibilities.
And looks like ever American native is getting this $2278 in his account every month. If you don't have a working girlfriend in Europe then life is more sort of hell. To share expenses you need a partner.I agree with those who says that they have seen more poverty in Europe and America. Also these countries are not asking every Tom Dick and Harry to land on their port and earn, they are looking for intellectuals not idiots.
Population is coming down not because they are highly aware or do not want children but because they are not able to feed children and don't want responsibilities.This trend also started in India soon we will be following them
You can run from problems but can not hide from them you have to sort things out.
