Elon Musk and Jeff Bezos are different to people like Tim Cook and Satya Nadella. Bezos took a relatively low salary when he was CEO of Amazon, and Musk takes supposedly no salary, because they don’t earn their wealth from a salary. Tim Cook doesn’t need to be more productive than some factory worker in China making 50 iPhones a day, because if paying him $100mn a year makes Apple $110mn a year vs someone else who takes $50k a year and brings Apple $2mn. They still take Cook because the profit is $10mn vs $1.95mn. Like I said, it’s about who can make the most money for the company.
I am very very sceptical about your claim that most businesses thrive without CEOs. Every medium to large company has a CEO, unless it’s a cooperative in which case they have a chair (and in large cooperatives, these chairs still command high salaries). John Lewis, the largest cooperative in the UK, has a chair who earns a salary of £990k.
And finally some people do dodge tax, not everyone does. In 2016, Tim Cook was awarded a $135mn salary, on which he paid $70mn in taxes. What am I supposed to say to this point really? Some people commit tax fraud, it’s still a crime. Maybe it’s not followed as much as it should be, but it’s still illegal.
