Well, yes, smaller private schools tend to have larger endowments per student. But Capital’s total endowment is $140m and lost 8% last year. I don’t think I’m going to sign up to trade places with them.
The more relevant comparables are other non-flagship public institutions, most of whom (like Miami) were late to large-scale endowment fundraising and find themselves behind as state resources shrink.
Another factor is that cultivating high-net-worth donors is a specialized skill requiring full-time staff who do nothing else. Landing eight- and nine-figure donations requires years of relationship building and lots of personal attention and meetings. The people who do that aren’t the same sort of folks who call me. Ivies have squadrons of these folks; most publics historically don’t and face pressure not to carry the extra payroll.
