I believe you are correct. If we are going to educate these whiz's, why not keep them?
Heck, all we'd really have to do is come up with real(!) enforcement of pay scales for H1b's, maybe even require they be paid 120% of what citizens would get, combined with a few high profile high penalty prosecutions of employer violators, and we would not need any limits on them at all, but would still get the benefits of hiring the really smart ones.

We are talking mainly Chinese and Indian for the actual useful degrees.
Many times the Chinese just send tech back to China illegally.
But also a huge number can be getting bogus liberal social science degrees or going to all sort of fake schools.
Going to immigrant school mills now is already now a top way for people to get here illegally.
