These billionaires/kleptocrats benefit from a legal and political system that doesn't recognize social murder or corruption as crimes, allowing them to get away with crimes against humanity on a daily basis.
No, they aren't “earning” their billions in wealth, they're just in a position to punch down, enslave, gaslight, and socially murder the public without recourse, and they've lobbied to make it illegal to fight back.
Like slave owners and dictators, every billionaire/kleptocrat represents crimes against humanity that people are gaslighted, beaten down, propagandized, and abused into not be able to even articulate let alone fight back against.
Oligarchy/kleptocracy is an abomination of a system and collective way of life that no one should tolerate.
Billionaires/kleptocrats should not exist.
