Or that business with a million employees could just return a greater share of the wealth to the employees instead of the owners, thereby avoiding triggering the marginal tax
Jeff Bezos is rich because his ownership stake (stock shares) are worth a lot of money on the stock market. He did not get paid out profits (amazon doesn’t pay dividends). There is nothing here than even makes sense to ‘return’ to the employees.
Meanwhile searching products on Amazon is still a shitshow and it's generally not possible to disable third party listings.
