Everybody can choose to donate, nobody should donate (otherwise it is also not really a donation if you should). Singling out rich guys to donate who do not donate could actually be counterproductive (since people just feel the responsibility lies with the rich guys). Encouraging everybody to donate small amounts of money might lead to a better outcome.
I don't really see how that adds up. In order to collect $50B, everyone in the US would need to donate about $150. Or, Jeff Bezos could liquidate a 1/3 of his net worth. A bit exaggerated, and a bit of a cartoon, but you get the point.
Plus, the utility of an extra billion dollars to a billionaire is basically zero. Fight me if you disagree.
Well Bezos donated 12 billion already, and who knows how much more he will donate. He probably couldn't donate every year that amount, so if you say in 20 years it is 150$/20=7.50per year which is less than a dollar per month (admittingly this is everybody in the US). This is a lot of money for a lot of people but I still believe the total possible donatable wealth of non rich people is orders of magnitude larger than rich people (couldn't find good stats, was looking a while ago)
