>Universities import foreign labor and they under pay given their monopoly

Given that there's hundreds of schools with thousands of grad programs to choose from, with none of them having more than a tiny percentage of the total market, this is not monopoly pricing.

It's simply supply and demand. People are willing to show up and work for the vast majority of these programs.

Are you sure about that?

Yes. This isn’t a monopoly, so it’s not monopoly pricing. That leaves competitive pricing.

Unfortunately you have no idea what you are talking about.

Then they take half of said external grant funding as overhead.

Indirect funds on grants need to be eliminated in my opinion. The GOP is a disaster at the moment in my opinion but introducing bills to eliminate them is one of the things they've done right. Indirect funds distort the purpose of grants and give perverse incentives to university administration and other funding sources.
