@doctorsex correct, the economic incentive is why it has gotten to where it is.

But the H1B and illegal migrant issue is tied, which is why we are where we are.

But - Musk is also in the position to get what he really wants ( top 0.1% talent - because HE can afford it ), and use that to starve other companies. So he can both do what people feel is right, come off as the good guy, and have a business win out of it.
