It's my understanding she donates a lot more than Bezos does. Consider the fact she has agreed to the giving pledge, giving away half of her wealth to charity similar to Buffett, Gates, etc. Whereas Bezos has not agreed, and I'm not aware of any time when he has donated billions. That may be the difference but I'm not sure as I haven't really seen any Bezos donation headlines that were negative, or any that I could remember at all for that matter .
