The idea with some seems to be that you're not a good manager if you don't treat your workers like dogs.
I suspect that part of the problem is that many with wealth and authority lack real experience with doing useful physical labor and so they lack respect for such work and those that do it.
My opinion is that the excesses of the early part of the industrial age opened the door for trade-unionism and its cousin, socialism.
The excesses of trade-unionism opened up the door to excessive government regulation and the creation of the welfare state (the step-child of socialism) and its excessive taxes.. The combination opened up the door to off-shoring factories.
And now we are seeing in places like China and Bangladesh the conditions that existed in much of the Western World in the late 19th and early 20th centuries.
Far better to recognize that we are all created in the image and likeness of God and to treat each other accordingly. IMHO.
