A lot of times you don't.
Are there some cases where a CEO makes 300 times what their lowest employee makes? Maybe. Do those CEOs make that every year? Certainly they do not. Are CEOs that make millions every year worth it? In many, many cases they are. In some cases, they are not, and the board of directors in these companies should deal with them accordingly.
The jealous left would have everyone believe that if not for these "greedy, money-grubbing CEOs who've somehow pulled a fast one on their employees," everyone would be paid more, and everything would be fine. Spreading CEO pay around evenly in most cases, would add very little to workers' pay.
But people need to look at the bigger picture here. We're supposedly still in a free market, which means that the markets drive salaries and benefits for everyone, not just CEOs. The Left wants to dictate where the upper end is, the company and the free market be damned. But I've got news for you, if the Left gets their way and puts caps and limits on CEO pay, your pay, at whatever position you're in today, won't be far behind.
