What you're sort of describing sounds like a boycott of our capitalist system. In theory, if we all could be self-sustainable and didn't need to participate in the current system just to survive, then I think it would collapse. How could it not? The billionaires are billionaires because we give up our time and labor for currency which we then reinvest in a system which transfers most of that currency to a select few at the top. If we all stopped participating where would the billionaires get their billions, and what would they even spend it on, if not our labor or products produced by our labor?

I can only speak for where I live but this kind of organizational boycott of the system isn't really likely to happen anytime soon. It's too difficult to organize that number of people into non-participation especially when there are not really any alternatives. It's not even easy to get people to give up listening to a certain artist's music if they've done a terrible thing. People are living shitty or difficult lives and need their creature comforts just to mentally get by. I don't blame them. There would have to be a viable, functioning alternative already in place which could absorb the needs of a massive number of people. It would take cooperation and compassion, and I guess I just don't see that in the cards.

Even if we did, how long would it last until the power hungry manipulated their way into building another version of the same system?
