big debate going on in California at the moment about how to get the billionaires to pay any tax at all.
They fund ther lifestyle by taking loans from their own company (which will never be repaid) Because a loan in theory does have to be repaid it's not counted as a 'tax event" and so the loan capital is tax free. If they sold shares in their own buisness they'd be liable for capital gains tax and maybe income tax.
As one of them once said " tax is for the little people" .
one of the reasons Musk is so successful is he DGAF what people think. He's got tax accountants providing him with his living expenses without selling stock or paying taxes and staying within the law.
