Probably isn’t that significant relative to wealth, and in Bezos case that wealth is built on the backs of warehouse employees who have to use food stamps and piss in bottles instead of taking a bathroom break.
Ah yes, I've run into the Earth arbiter and judge of significance of charitable giving.
Some days I wish Bezos et al would reduce their philanthropic giving to $0 for a calendar year and see what people have to say about their previous stingy behavior.
