So we (as in "various elements of US society") are paying to educate people, and then are sending them back where their home countries benefit, while the US does not. It's so dumb.
There are some cool exceptions, like some programs where students educated in the US are required to go back to their home countries. The idea is to help raise the level of education in countries where the higher education system isn't well developed or funded, and I think that sort of thing is an admirable goal. But it's so bizarre that we, for example, complain about supposed Chinese academic espionage, and complain about brain drain, but simultaneously make it really hard for international students to stay in the US after they graduate.
Look at postdocs - the US gets them at a pittance, they are more productive than PhD students and rather mentor them; and unlike graduate students, are usually overwhelmingly foreign nationals.
One PhD student costs a professor about $100K - $200K per year. A third of that is stipend and the other two thirds is... well, in CS I'm not even sure. A good bit of administrative welfare AFAICT. (Universities don't pay FICA taxes for grad students and grad student healthcare premiums are actually more of a subsidy for the risk pool of the aging faculty/admins than an actually half-reasonable benefit for the grad students.)
The US graduates 2K PhDs per year, of which >60% are foreign nationals. So we spend something roughly like (2000 * .6 people) * (150000 $/person) = $180 million per year. So a couple billion per decade.
Now... we do get folks with CS BS degrees for 1-5 years at $30K/yr, which is a fucking steal, and at least a great universities they are often from the upper quarter or so of the undergrad distribution. So maybe the students are also paying in the form of subsidized labor. But we do spend hundreds of millions per year in any case.
All of that said, as long as universities are staffing mathematics departments with shit paid ad juncts it's kind of hard to argue that our country is failing to compete due to a lack of phds...
No. At least, not in CS. What sorts if things would you be referring to? Compute? Honestly you're better off with a trivial cloud grant than trying to use the slurm cluster with a dozen ancient gpus for hundreds of faculty to share. Office space? Your average dilapidated cube farm is LUXURY compared to the sardine situation grad students put up with. Robotics hardware? Doesn't really scale like that. And... those are the only three things needed for like 90% of CS research. In CS, precious few dollars other than the stipend go toward anything useful. As far as a faculty member is concerns, that money money disappears into a pit.
(What's going on is that the PhD stipend is fixed by the funding agency, and the university squeezes as much as possible away from the professor/student. Just armies upon armies of assistant deans doing not much of anything while the grad students toil away doing the only useful work in the place for rent and pizza.)
> The US graduates 2K PhDs per year, of which >60% are foreign nationals.
It looks like across fields, it's ~55k PhDs/yr, so the "Billions" quote was probably right.
So how do you want to account for labor costs? After they leave, the work got done and the workers got paid. Both sides benefit from this arrangement, though you can certainly argue (and many do) that the benefits should be split more fairly by paying the workers more.
Separately, the US would benefit from letting them stay and do more work. But that's generally the case for any immigration restriction. They get in the way of mutually beneficial private arrangements. US employers can't hire people who are willing to work for them, and the workers strongly benefit from being able to work in the US. Immigration restrictions are all about the government getting in people's way and the various justifications people make for continuing this interference.
Certainly, there has to be consequences to the countries losing minds & bodies.
Which is true. At the same time, what’s been his contribution to Bangladesh? Nothing, aside from a bit of trivia I tell people when I show them around Chicago.
If you take one of Dhaka's best and brightest and remove him/her...Dhaka gets nothing.
Like it or not, there is a darkside to USA immigration policy, just because its been normalized doesn't mean it's not there.
