Phil you don't really understand why western democracies have such high immigration policies do you?
Once women in the west are free to chose between having children or working, a lot of them chose not to have kids at all, a lot chose to limit their reproduction significinatly, only a few go onto to become welfare fraudsters. Whereas, your poor migrants from shit hole countries with high infant mortality come from the culture of having large numbers of kids to cover the inevitable infant deaths is normal and encouraged. Working class women who have large families are revered in poorer countries but in the west they are portrayed as stupid, lazy and unworthy of state support. In Aus, only 60% of women have children, the UK wouldn't be far from that number, those that do chose mostly to have 2-3 kids, leaving the issue of an aging population and a declining workforce to pay the pensions of the idle grandparent class.
When you finally go to the old pilots home, chances are the guy wiping your asse will be some sort of non-anglo ethnic.
