The thing that gets me is that he could make himself last on the list if he reduced the operations of his orphan-crushing machine by like 90%. Not even 100%, just 90%.
He could hold onto more wealth than he could spend in a lifetime. He could still live in a ridiculous mansion and shit. But if he gave away 7 of that $7.5bn on actually good causes that he wasn't profiteering from which directly benefitted the world then he would almost certainly be considered one of the rare "good ones" and his chances of getting cleaned up in a wave of uprisings would be very, very low.
But no. He's going to have panic attacks due to a latent guilty conscience but he isn't going to actually do anything about it. This headline has the same energy as an oil executive who publicly complains about a heatwave imo.
