So, if you believe consumption is the issue, rejoice! It seems to be a problem that will resolve itself in a generation or two.
A billionaire consumes less of their income and invests more than a regular person. Wealth is power, but virtually everyone would spend on the same things.
A billionaire has the power to affect policy in a way that the average consumer doesn't, and is more likely to use that influence to make themselves richer than to push policies that benefit everyone.
Velocity of money matters. Builds. Bezo's sucking up wealth instead of paying workers retards the economy.
There is a reason Smog the Dragon is 'villian' prototype told by humans since forever. I get modern American conservatives think it is a model to emulate and is actually the highest for of being, but it's not.
And the super rich simply can't consume that much. Bezons isn't eating a thousand times as much as a millionaire. If his kids spend their lives being unproductive, it's only a tiny handful of wastrels. Mansions, yachts and large private airplanes might be a bit of a resource sink I guess .... but how does paper wealth cost society real resources? It's like being made at someone with a rare monkey gif
