They have been doing it for years under internship programs.
Which are another of the great rackets of higher education. It used to be you got a job, got paid, and learned something.
Now, you get an "internship", don't get paid, and learn something. But, here's the kicker. At some universities the company who "hires" the intern pays a fee to the university, and the student pays tuition while he is "interning". Now isn't that a deal for the university, they get paid while you work!
