I'm a professor at a regional university. Not a big name school, but we have about 5,000 students. We would be bankrupt if we told students we'd only be offering classes online this fall because students, by an overwhelming majority, want the in-person experience. We know we would lose enrollment if we went fully online this fall, and the drop would be significant enough for the university to declare bankruptcy. Harvard, Princeton, Stanford and other big names have enough reputation and big enough endowments to weather a storm of a temporary drop in enrollment due to shifting instruction online. Many universities cannot.
