This guy better stay out of any commercial or financial transaction for his own welfare. Her may know something about politics, but his grasp of economics is horrible. If Elon had to pay $50m pa in tax every year, it would, within a period of a decade, force him to lose control of SpaceX, and probably relegate SpaceX into the realm of just another arms and space contractor. Employment at the firm would probably halve, along with a loss of direction, as the "professional management" steers it into "safe" waters. The government would, as it has the propensity to do, spend about 133% of the tax paid by Elon, getting even further in debt as the academic institutions build even larger administrations. The country would sink even further into the quagmire, emulating European decline. These people...
Brad, a 5% tax on Elon's trillion net worth would literally pay for free college and trade school for every American.
And with the market's growth, he still would be worth over a trillion dollars!
You don't think that's worth it?
