Some people live in a pressurized bubble for a month for saturation diving. If the price is right you can get someone to do almost anything.

That is true but I think the salient observation here is that it's only realistic to pay so much for education. So either you can't have children in such a town, or you're forced to homeschool, or (I guess what's being suggested is) you import someone willing to work an undesirable job if it gets them into the country.

I think there's an important difference between importing labor to undercut qualified americans in a populated area versus importing labor to do a job that the vast majority of qualified americans will have no interest in at any reasonable pay rate.

It doesn't matter how much money you have if you can't spend it.
