I get the history as to why we got to our current economic situations, but no one is arguing for a system that casts off current economic issues that are pushing humanity towards destruction. I’m not saying this can happen over night or even within our current life time, but it’s obvious that capitalism and even socialism has reached the end of their usefulness.
I’m not sure you know what post scarcity means.
Imagine a world where nobody needs to work, but everyone can still have any material desire filled at any time.
Think Star Trek. Unlimited energy resources, combined with replicators which use that endless energy to create unlimited stuff without any labor required.
It’s also important to note that a lot of that scarcity is artificial. Sure, we’re far from post scarcity, but strife is exacerbated by capitalist systems in all but the most privileged.
