When we say billionaires are evil, this is mostly what we mean. Inaction is just as bad as bad action, if you have the means.
There have been a handful people (ex-billionaires) who apparently got the message and decided that a few hundred million was more than enough for them and gave the rest away (and actually did it right away instead of in a “pledge” when they die so their children can curate the non-profits that will inherit their billions). Mckenzie Scott is one.
Turkey is very similar in this regard. Progressive cities, backwards countryside.
