But we aren't hunter & gatherers anymore (not that back then there were capitalist). That age is gone (for now).

Nothing about capital (something someone can own & accumulate) is required to have and sustain cities, technology, services, etc. And it all comes from the propaganda that people are lazy & don't work if they don't have to (the opposite is true, but the distinction is that often what you want to do can't be monetized for various & fairly random bullshit reasons - like, you will always find people that will want to bake/cook/serve, but most of the people that would enjoy that just get a different job that pays better & the ones that don't like it get stuck with it ... and we all get the worst part of that deal, even as consumers, except the people with incentive to maximize sales & minimize wages ... like that is a good long-term goal for society or something).
