I would point out that there are plenty of people in managerial positions who do absolutely want to treat their people like crap and derive great pleasure and satisfaction from doing so.

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".
