If there is anything worse than the tyranny of greed, it is the tyranny of a machine that's trying to optimize you 24/7.
I'm failing to see how caring about billionaires is suppose to help everyone else. The current American society, via neoliberal economics, is already optimized to help the billionaires (hence why they extract all the wealth and why income inequality is at its highest in the US since ever).
The purpose of the system is what it does. Or in this case, the actions of the billionaire class and their capital are their values and morals.
