When you have an organisation full of people creating worth that you can cream off, you've bought a few houses, yacht, fast cars. You get to a point where you realise you're not leaving anything of value behind and think "if I pay for a university building then I've created a legacy of education for generations to come".
TL;DR it's like a shiny name plaque for billionaires.
I get it - and I agree with the reasoning - but I want to leave a shiny new park with my name on the plaque, not a building in an overpriced university.
