You know, throughout the world, throughout history, when countries get rich, they stop having kids.

If you have waves of immigration, you better figure out a way to turn those immigrants into red-blooded Americans, or else you end up splintering the society.

The best way to achieve self-esteem is to do something worthy of esteem.
