If that's your best argument, billionaires are in trouble.
If that's your best argument, billionaires are in trouble.
(And keep in mind that FSD cars are 8 times less likely to get in an accident.)
Billionaires get that way by making things and services that people want to buy.
Very few normal, sane, and well balanced people are capable of doing the things required to become a billionaire. That level of wealth requires such a massive disregard for the well-being of the rest of humanity that it leads to some terrible outcomes. Being so wealthy that nobody can really do anything to get in your way is inherently bad for the human mind.
And you can't have democracy (everyone has an equal say) when you have large wealth inequality, because wealth is power. In practice we have a few billionaires who control everything... that's not democracy, that's oligarchy.
