Why doesn't anyone care about population control?
No country wants to limit their growth?

$5,000 cash to be sterilized
The western world is slowly sterilizing itself for free. Look at Italy, the cradle of western civilization, they have a birth rate of 1.0 children per couple, far below the replacement rate of 2.1. This means that instead of many grandchildren to care for their grandparents, you have 4 grandparents, 2 parents and one child. An invertd pyramid.
Compare/contrast to eastern "civilization" (middle eastern). Let's even compare it in Italy. The average birth rate to middle eastern immigrants in Italy is roughly 8 per couple. It doesn't take a demographic savant to realize that native Italians will be an electoral minority in less than 12 years.
In the US, our birthrate is just barely at 2.1, but the immigrant masses come here and maintain an 8.0. Our demographic shift is less steep, but the numbers don't lie.
So, let's NOT pay folks to sterilize, unless we want to make it part of the immigration contract. THAT, I might be able to get behind.
