Even taking a fair question

I think that society as a whole is better off putting 18-22 year olds on islands of college campuses, housed with each other, as opposed to housed with people who are statistically far more likely to be at-risk. Not all colleges are set up this way, but even in the urban campuses where students mostly live off campus, society is likely better off with them living there, with other young people, than with their parents.

If there are at-risk faculty, take special precautions. At-risk staff would need to be dealt with differently. Ultimately, the working-age population that can't safely return to work probably need to be put on disability.
