Trump to impose $100k fee for H-1B worker visas, White House says

I think there’s plenty of interesting debates to be had about immigration policy and its effects on the labor market, but one thing worth noting here is that the primary problem that damn near every other country on earth has isn’t immigration, it’s brain drain.

A core strategic strength of the US over the last century has been that everyone with any talent wants to come here to work, and by and large we’ve let them do so. You can argue how well that’s worked out for us - having worked with a great many extremely talented H1bs in an industry largely built by immigrants, I’d consider it pretty positive - but it damn sure hasn’t worked out well for the countries those talented folks came from.

I don't think it follows that preventing that brain drain would have lead to appreciably better outcomes for those countries. The real sucking factor for the united states is the second to none availability of capital to spend on R & D. If you keep the brains where they were raised, there is no mechanism for them to actually turn their ideas into fruition because there is little funding to support this either in private or public sector. The reason why you hear about research talent going back to China is because they are offered PI positions and generous startup grants or something analogous in most cases, with the government there committed to invest billions in research. You can't really expect that in the global south. You can't even really expect that in Europe in a lot of cases.
