First of all there is no such thing as a free market. Universities advertise good careers if you go through them, and I am not sure these numbers are as balanced as they could be. Second even if it were, there is a terrible imbalance of power between students, which are distributed actors with little to no individual power and little information or experience, vs a much bigger actor with more information and a lot of power in such a relationship. (From a comment in the other thread about this subject on how this particular market was skewed: https://www.ineteconomics.org/perspectives/blog/how-why-government-universities-industry-create-domestic-labor-shortages-of-scientists-high-tech-workers https://www.ineteconomics.org/perspectives/blog/how-why-gove... ) And janitor is in all likelihood a decent job with union protection (good for them).
