DD - great post. We're closer in thought than may appear at first blush.
I agree - my plan isn't something most can do but believe more could realistically do it than you're giving credit for. This year, with no FA, UR would set you back $72,450 for a year. By the time my son is in college, a school like UR will probably cost half a million all-in. Not sure that's exactly "something most people can afford."
The model of having every luxury available with huge fixed costs. Effectively the arms race to have the latest science center, the dorms with heated floors, lazy pools for dorm complexes, dining halls with celebrity chefs, singles with private baths and housekeeping. Very little of this impacts the quality of the education (and subsequent earning potential of grads) but rather impacts the price of that education, reducing the ROI.
In 1988 private four-year tuition (not including room & board) was $15,160 (

In 2018 (I know, slightly different time frames, but trying to quickly bring some facts to support my opinion, rather than just providing my $0.02), tuition was $34,740 or 129% increase. UR's annual operating expense has nearly tripled since 1999. In 1999, net tuition covered 48% of annual operating expenses. In 2019, that number had dropped to 37%. A 7% net tuition decrease and UR would have been in the red from operating expense (to be fair, $37M was depreciation, so the university could cover day-to-day expenses just fine with 7% tuition decrease for a while).
I think schools are going to have to find ways to provide a more customized, tailored, a la carte model. I whole-heartedly agree with Fan in that JCs will see a surge in enrollment. I also agree with your point on social skills/soft skills, which is one of the true benefits of going to a residential college. As a hiring manager, I can attest to your less than 1%.
I'm not going to pretend to have an all-encompassing solution but don't believe the current model is sustainable.
