^Yes, I am more worried about public education (both tertiary and K-12).
I do think many tuition-dependent LACs, with small endowments, lower selectivity/higher acceptance rates, a more traditional slate of majors, and low alumni giving will probably close/disappear/merge in the future. Colleges like Sweet Briar - they were able to reopen, but they had all of the above problems despite being an excellent college. As someone here on CC said, when your acceptance rate is already 80% and your yield starts going down, you don’t have much of a pool to dip into. Amherst or Swarthmore, should they find their yield dipping, could theoretically expand from a 12-14% acceptance rate to something in the 20-25% range to make up for lower yield. Plus there are always going to be wealthy parents (American and not) willing to pay a lot for an education they consider premium.
But it won’t be because they’re not good in STEM; which majors are hot at a particular moment changes every 10-15 years or so. When I was in college, there wasn’t as much of an imperative to major in STEM careers - most of the technology companies that are big and dominant now either didn’t exist or were mere shadows of what they currently are. (Of the big five, Amazon and Facebook were much, much smaller; Google mostly did search and none of the other cool stuff they do now; and Microsoft was in a bit of a rough period. Apple was beginning to rise, but this was pre-iPhone.) The common wisdom there was to major in what you love and the money would come, and the hot career at the time was lawyer, not software developer. And I graduated from college less than 10 years ago.
With falling investment in public universities and colleges state-to-state I do see more of them, in the future, offering online only or majority-remote educations - perhaps with a few exceptions at state flagship universities, which may ironically become unaffordable for the majority of middle-class (let alone low-income) state residents. That’s already the case in some states.
