But that's not the point. They aren't going to starve. It's a wealthy country, and proportionally, relative to people in other parts of the world, more of them can mooch off of friends, live off of family savings, etc etc.

The point is that *proportionally", at all income levels, Americans are much wealthier than immigrants from Central or South American countries. And I think most quantitative labor economic studies back me up on this point, that there simply aren't enough Americans willing to work the kind of hardback-breaking jobs that immigrants are doing right now.
