I don’t think 100 million will buy you a hill of beans in US politics. And I don’t think they’ll betray their class interests for any amount of money - what’s the point in taking a $100m bribe if it means there’s fair taxation and more equitable living that prevents them being top dog with that money?
Absolutely this is why. And owning stuff isn’t a job - only workers contribute to society.
Unfortunately, having bourgeoisie rulers and landlords is the central underpinning to capitalism.
