My impression has long been that the endowment per capita metric provides about as good a ranking as any of the third-party rankings within a category. Where it disagrees with US News, it usually matches my intuitions; and where it disagrees with my intuitions, I usually learn that the college in question has a better reputation than my impression. It doesn't do a great job comparing across categories, but then, neit…
Some top colleges don't have alumni/legacy preference so that endowment measure maybe gets skewed away from them. MIT and I think Caltech.
Maybe they'd be richer if their admissions was more open about taking quasi-bribes, but I suspect you're dramatically underestimating the orders of magnitude of difference that appear on this metric. You find clear tier gaps.
Don't get me wrong, this is a silly proxy metric about three degrees out from anything you'd actually want to know. But it gets surprisingly good results for how simple it is to tabulate.
