Go not by what they say but what they do, and I've known plenty who have treated their staff like utter crap, from screaming abuse at them to ignoring them to undervaluing them to psychological bullying and more. I guess all your workplaces must be like heaven compared to what I've seen.

I don't understand where you're coming from. To me it's a decent and useful post and you are just tearing it down for no reason I can see.

The world would be better without such people, but they certainly exist and seem to have a habit of floating to the top.

For such people it might not actually occur to them that treating people like crap may be counterproductive to other goals like profit. Years ago I recall a family member telling me about their then boss proudly stating something along the lines of "if my workers are happy then I'm not managing them properly, employees need to be miserable to be productive".

The "decent" word is carrying much of the weight in your argument.

Not everyone is a decent person, but if being a decent person is actually a way to become a good manager, then the statement is not vacuous at all. Given the conventional wisdom that CEOs have sociopathic tendencies, the statement may be flat out wrong even. I just don't think it's obviously vacuous.
