Billionares shouldn't exist. We shouldn't just tax them for the revenue. We should tax them to limit the undemocratic power that comes with excessive wealth.
Agreed. Humans evolved in a tribal, local community leadership system. To have as much wealth as millions of people that you never interact with should not exist as a person. It is against the system principles of humanity; either create a new species and turn the billionaires into them, or balance the system.
