No. You are entirely wrong about the futures of the LACs with good reputations.
You seem unaware of what the academic market looks like. Except for a handful of fields, there is an overproduction of PhDs. The number of really good applicants that these LACs are getting for each position is enormous, and these are faculty from the very top PhD programs.
You also seem to be entirely unaware just how coveted positions at good LACs happen to be.
Add to that the fact that graduates of LACs who do PhDs tend to want to become a faculty member at a LAC. Since LACs, especially LACs with good reputations, have, on average, more than 10% of their students who end up doing PhDs, there is a supply of potential faculty at LACs which far exceeds the number of faculty needed by these LACs. Every year, a number of students, equivalent to 10%-15% population of the college around a decade a go, are getting PhDs. That is roughly around 80%-100% of the number of existing faculty. This is every year, and, of the 200-400 faculty members of each college, only a few are replaced, maybe 2-3 at most. So each year, there are 50-300 new PhDs who did their undergraduates at a LAC for every position at a LAC which opens. That is without considering the number of students who did their undergraduates at other types of colleges who are really interested in teaching at a LAC.
The job satisfaction of faculty at LCs with good reputations is high, as well.
So no, there will never be an issue attracting, hiring, or retaining faculty. There are failed searches, even at top schools, but these are, invariably, the result of internal departmental issues that are as old as search committees, and are actually less common, proportionally, at LACs.
As for attracting students? Even considering the fact that most applicants apply to multiple LACs, there are far more excellent applicants to “top” LACs than there are places for them.
So no, Bates, Middlebury, Williams, Vassar, Hamilton, Kenyon, Denison, Carleton, Macalester, Pomona, Occidental, etc, will never have a problem finding excellent faculty or excellent students. I do not understand what makes you believe otherwise.
On the other hand, small religiously affiliated colleges and small rural colleges with really limited name recognition outside their immediate area, especially in rural areas in regions which are economically depressed and/or, with dropping populations, will continue to close. The communities that they have served historically is smaller and poorer than it was, while the richest people in the communities are more likely to attend a college somewhere else.
That actually makes absolutely no sense. You’re essentially saying that the 486 colleges that have MORE than $50K per student in the endowment are at financial risk? Essentially, you’re saying that having a LARGE endowment puts a college at financial risk?
Please re-read and clarify what you are trying to say here, because I don’t think that what you wrote was what you were trying to say.
In any case, it really isn’t simply endowment per student in any case.
