That's an easy one, less money to administration

Taxes? These students will more than likely pay more taxes than they cost

Absolutely fewer graduate students. The market just isn't there. There are exceptionally few professorial positions and commercial positions benefiting from graduate degrees available relative to the number of graduated students. This is true in every single field. The whole system is a giant scam against the students who are lied to aggressively by their schools for cheap labor.

I think postdocs would be the best population to trial a basic income program. That might mean taking money from every one else. Oddly, I used to have the opinion that science should be a positive sum endeavour.

Non-disclosure: If there were such a program, I might have considered becoming a postdoc.

- grants are worth less than they were before (https://drugmonkey.scientopia.org/2020/12/16/updating-the-er...)

-Profs receive money from several other sources - especially patents and are not reliant on as grants for incomes. As such I don't believe it's a massive issue

-Uni's take massive cut from grants (+50% in some cases) so that would be a starting point, especially since a grant now is worth less than one from 2001. (https://www.quora.com/How-much-of-a-research-grant-does-a-un...)

-Labs rarely get money from undergrad fees which are already insanely high

-Science at the current scale (at least in my area of biology) would stand to benefit from more grad students, the infrastructure just isn't there. This is ignoring the pyramid scheme that is grad school.
