All in all, the result is billionaires hiding more than one-fifth of their income from the IRS. Yup, the 1% evade taxes so much that they account for more than a third of unpaid federal taxes.
Between 1980 and 2018, the taxes paid by US billionaires (measured as a percentage of their wealth) decreased by almost 80%.
And there are "evil" billionaires. The billionaires mentioned here are from the western world. In some countries (i.e. UAE) billionaires treat their workers like slaves. I admire Elon Musk very much for what he achieved, it's almost superhuman but contribute to society by paying taxes!
