I like the idea of Charity adjusted rankings rather than current rankings. My thoughts:

1. It's unlikely to gain significant traction.
2. Is already done in many ways indirectly including names on schools/buildings/etc, The Giving Pledge and other forms of charitable recognition.
3. Highlights how much value & prestige we place on money.
4. Demonstrates why we should work towards a fairer and more efficient economic & monetary system that internalizes externalities so that individual wealth better represents net contributions to society.
