Oddly specific to call out multi billionaires. So a single billion is fine? The threshold is at 2?
You could probably amend this to "billionaires", instead of the qualifying "multi billionaires".
ETA: You know, I was thinking, just because I qualified it with "multi" in front doesn't really imply that single-billionaires aren't evil. I didn't specify that serial killers are evil either, but I don't think me not specifying that implies that I think they're fine.
