People who earn money pay taxes
While at Amazon Jeff Bezos considers his worth to be 80k a year hence he was paid that much, and paid taxes in that salary.
If someone becomes a billionaire by being paid 50m a year for 40 years and paying taxes on that income then congrats.
Bezos has paid $billions in capital gains taxes.
About 1% of the wealth he’s accumulated
Has he earned his wealth over 40 years at an income of 7b a year he’d have paid 115b in tax, not 3b.
