You’re right that material conditions are the main contributing factor in the creation of billionaires, but why do you think it’s the only factor?

There were thousands of individuals who had the right connections, the right age, the right group of friends, etc. Only a small percentage become billionaires. Do you think this selection process is purely luck?

I think there is something that sets apart one class of obscenely-wealthy oligarchs from their slightly-less wealthy counterparts. Maybe it’s sociopathy, or adhd, or extreme greed. It definitely looks like mental illness.
