I was not at all advocating for Marx or that quote.

I'm just pointing out that it's largely a universal truth that if we want a functioning society with food and roads and electricity and houses and internet, a lot of people are going to have to do something they would rather not do.

The "greedy capitalist" is more about how the work is coordinated. We have a market-based system where work assignments are more or less voluntary where he who signs the checks sets the work. But I am not volunteering myself to going back to a manorial or subsistence agriculture society.
