This is a conflation between an important position (being able to resolve disputes and push decisions and direction) and being an important person. CEOs have skills, and have invested heavily in training those skills (if they aren't terrible) but those skills are not skills unattainable to the normal person, society just doesn't need very many people with those skills and the apparent value those skills create via business decisions appear to pay off handsomely. But that $50 million the exec's decision has made for the company isn't solely due to their work, if the company didn't have programmers and labourers and marketing and manufacturing to support the decision and deliver on the decision then that $50 million wouldn't have been earned.
Their decision is important, but their involvement isn't worth the full value the company receives based on making that decision, because without the supporting labour their decision may have been genius, but it would have netted no profit to the company. I think this sort of highlights what I consider to be a real issue with how we evaluate personal value in the modern world and why assets are becoming so concentrated in the hands of so few.
