My guess is that many larger universities will get a haircut on their tuition income since many students will opt for community college for more basic courses....why pay full price, especially online?
Coupled with loss of income from refunding the spring housing costs, and this is going to put a major cash crunch on higher education.
And, as
@Mark from MA points out, when people pay full price for an online class that was supposed to be in person, people are absolutely not going to take it sitting down.
Of course, at many universities before the whole Covid-19 outbreak, online classes cost more than in-person classes anyways, so maybe that precedent will mitigate the ability to successfully challenge it.
Since the major inflation of college tuition in the last 30 years was largely driven by universities making available more amenities that can ONLY be experienced in person, sure would hack me off to keep cutting the same size checks for online classes.
