It's not like there's a requirement here that the doctors are going to work in the non-profit sector. It's not going to make the field less overworked and toxic. The students at this school have the same demographics as every other medical school.
Given that nearly all of the students who graduate from a medical program end up in the top 10% of wage earners, this seems like a temporary alleviation of financial problems for a very small cadre of well-to-do.
I am happy Dr. Gottesman felt such an affinity for her former employer, but it kind of strikes me as an ... uncreative(?) deployment of a billion dollars.
