A guy donates an engineering complex, and every engineering student on that campus gets to take advantage of said complex and its resources. Guy donates a new business school building and every student on that campus can take advantage of said building and its resources. In exchange, the university lets in two girls, their daughters or whatever, who might want to major in Art History and French, and coincidentally will likely be inheriting a few hundred million to upwards of a billion dollars in the future. (Future donors.)

It's a fair trade. I'm not wealthy on that level, but if I were calling the shots at a university I'd make that trade every time.
