Yeah, just scan through the list of names on The Giving Pledge Wikipedia page (https://en.wikipedia.org/wiki/The_Giving_Pledge https://en.wikipedia.org/wiki/The_Giving_Pledge), which helpfully lists their net wealth so you can see their failure at a glance. Also note that the pledge is only to give away "at least half" which is pretty unambitious for a multi-billionaire. If you have $10 billion and give away $5 billion, you've made no impact on your own life and sacrificed nothing. It is not comparable to someone with $100,000 giving away $50,000.
