It's a basic concept of economics that for one man to be rich, another has to be poor.
For a manager to make money, he has to make workers do things, then give them less money for doing it that other people are giving him for making them do it.
The rich get richer, the poor get poorer.
I live a reasonably happy, healthy and safe life because people in other countries are kept dirt-poor by massive corporations, so they can supply me with goods and services cheap enough to lure me into buying them. And with a great enough gap between cost and value, that the CEOs of those companies can fly around in jets.
And you know what? Strangely enough, I'm okay with things that require no effort on my part and make my life better.
