One facet of the problem is that Americans generally have kids when they feel they can afford them. Keep Americans poor enough by forcing them to pay for other people's kids, and they (the Americans) won't have any.
Uh, not me. Couldn't afford any of my kids(3) They are all grown; One lawyer, one trauma nurse and my son graduated and has a B.A. You will have to exclude this as being un-American. Sorry!
