Pell grants go directly to students, so what do you mean about the universities spending it wastefully?

Pell grants are for education, it makes at least some sense they go universities. I’m not sure if you’re implying they should go to 2 year or vocational schools? Private, for-profit non-university schools are a large problem in the U.S. in that they have much lower financial returns for the students who attend them, and much lower quality educations. There’s an entertaining piece by John Oliver about this, among other sources.
