If the white indiginous population had continued to have large families (instead of stopping at say 2) after the second world war, we would not have had to bring so many immigrants into this country who DO still have large families.
This country needs young people to grow up, work, and pay the taxes, for the ever aging population in this country.
We should be proud of people having 10 or 15 kids, not despise them.
I bet if you all looked back to your ancestors 100 years ago most of them would have had about 6 or 7 (or more) children.
