Periodic reminder: there's no such thing as a 'good' or 'admirable' billionaire. Good & admirable people don't become billionaires.
If you haven't seen it, watch Anand Giridharadas explain, brilliantly (ironically, at Google's HQ), why billionaires' 'generosity'... isn't generous: https://yewtu.be/watch?v=d_zt3kGW1NM or https://www.youtube.com/watch?v=d_zt3kGW1NM <- one of my favourite talks, ever. (probably Anand's last at Google 😂 )
