The issue here isn't that no CEOs works, or that all CEOs are lazy, its that the disparity in the ratio of wages to labor. CEOs receive more wages for less labor than the overwhelming majority of other workers in their company. A CEO doing as little labor as possible not to get fired would still make dramatically more money than an average worker doing as much labor as they can without dying. An average worker can give 100% and still note make enough to live, while a CEO can give 1% and still live more comfortably than those they supervise.

CEOs aren't the root of the problem though. It's the company owners that are stealing the value produced by your labor while contributing nothing themselves. The CEO gets the wages they do to keep them standing between the owners and you.
