If these guys had less complaining workers, people willing to contribute more so in their enterprises, workers who are happy to make their products, it would be fine.

I am not sure that would work. Happy people start to get self-aware and then start to make demands. People who are suffering one way or another are easier to control.

Look for example at how people behave after a war. They work together, build stuff together, do everything to manifest peace. Look at how they behave a few decades later ... it has fallen back to in-fighting. Once everything is in order again, people fight among each other. Neighbors fight for shit like wrongly places trees, some build gangs and move around to destroy stuff just for fun, etc.

Humans are shit. We are just not made for being happy.
