Y'ever seen a Carnegie library? Or a printed program with a list of donors?
The leaderboard for charities is having public works and spaces named after you. It's why you'll never find a 'Mrs. Deras' Third Grade Class of 2012 Pavilion.'
As it happens, it has the exact effect you mention, at least according to the wealthy.
Fundraisers have learned it is easier to raise money in the name of a donor and easier to raise money when others see that you have raised large gifts.
The leaderboard has been there your entire life, we've just never been wealthy enough to consider ourselves part of the game!
