Have you ever managed an intern? Inexperienced labor often has negative value-add.

> Make the business students hash out contracts with vendors

A second semester senior without a job lined up negotiating a seven figure contract... what could go wrong?

> IT students handle the networking

This is already a thing at most colleges.

> mechanical engineers the boilers

Might be possible, but could also be a disaster.

> hospitality management majors dorm maintenance

Students already do work in dorms at front desks and so on. Business majors aren't qualified to do plumbing, electrical, etc.

Students who are qualified to do plumbing and electrical are probably better off selling that labor on the open market.

At the end of the day, the other basic problem is that at most colleges, most college students who need work can get better-paying work than the sort of work that's available on campus. Why work in Uni IT over the summer if you can get an internship literally anywhere else that probably pays better and could become a full time job?
