>If Paul can figure out a way to filter in the great developers while filtering out those that are only coming to make money, then I'd be completely behind his plan to let them all in.

You are implying that all (most) of the American programmers are exceptional. That is not the case. If you have a good team, you had to do it yourself, weed out fakes from real ones, didn't you? The onus is on the company/manager who is hiring to pick the right ones whether they are already on H1 or before company files H1 for them.
