Also you probably need to factor in living allowance if supporting underprivileged and once you give a scholarship you're looking at a 3-6 year commitment to that person.
Plus if you want the scholarships to run in perpetuity you can only spend at a rate that keeps the endowment at certain payout rate that does not reduce its value + inflation
So at say 6% being spent a year, divided by $80k to cover tuition and living cost, average 4 year course commitment your looking at 338 new scholarships a year.

Or a daughter from someone in Detroit (went back to find the details of that anecdote and got locked out from paywall).
