And on the flip side a CEO can improve and expand many people’s careers and therefore wealth.

A dictatorship like Mao Zedong, Mussolini, Hitler, etc can flow all the wealth and power to themselves, oppressing the people under them.

The point it: You can’t talk about best case scenario of one and not the other. Usually, as it’s human nature, both are going to sequester wealth and power for themselves over the people under them, but a bad dictatorship is leagues worse than a bad company/CEO.
