you can't explain that basic concept to the free traders here - they just do not understand how globalism is depressing US wages, and toss in the chinese currency peg which we seem unwilling to fight to have them drop, and its just makes no sense for americans to even consider those professions any more. you can make far more money being a waiter at a busy restaurant.
Maybe because "free traders" do not accept the notion that our wages are falling on faith? What is it with you guys?
