Isn't that normal? There's a reason so many buildings have a person's name on them. Carnegie Hall, Enoch Pratt Free Library, Guggenheim Museum, The Getty, The DeYoung, Coit Tower, ...
AFAIK Half the buildings on any college campus are named after the donor that paid for it.
You want hospitals, how about the Huntington Hospital, Sutter Hospital, UCSF Benioff Children's Hospital, Helen Diller Medical Center, I'm too lazy to go look up more
Yes, that's just one of your points but if you're reaching that deep to find fault it detracts from your other points as it makes them suspect.
Maybe you and I and countless of other people chip in some money at the end of the year. (in fact in proportion to our income we donate more), and I don't see ordinary people forming a union to name a hospital, we just click the donate button and go on with our lives. Like Chuck Feeney btw, to name one very wealthy person that is way less vain.
