So, the simple truth is that there is a very high demand for a good CEO and a very small supply of them. That is the reason they can demand a particularly high salary.
The idea that CEOs don’t work harder is ridiculous as well.
CEOs are responsible for thousands of people, stores and even billions of dollars. A single mistake by a CEO could cost a company millions and cost several jobs. These people work constantly, they rarely have a vacation. They have to be available at all times because any crisis is going to happen.
It is not being said that employees don’t work hard, but it should be noted that a CEO works just as hard, in fact sometimes harder in even more areas, than these employees.
