The brain drain is heavy in the other direction (towards the US from elsewhere), and doesn't seem to be slowing down. As long as the US can pay far higher salaries than other countries, the social benefits are irrelevant for the high performers.

The high skilled people would earn far more in the US than elsewhere, and get a lot of benefits as part of their high paying job. It's difficult to see the brain drain to the US stopping, let alone the reverse brain drain you forsee.

I will add to your point that high salaries + not losing it all to taxes is the kind of equation that matters. Some developed countries with strong social policy have reasonably high salaries, but much lower after taxes.
