The fundamental difference here is that leftists (as I am referring to, and will further refer as italicized to save time) have analyzed Capitalism and believe it to be fundamentally unsalvageable, only band-aids and stop-gaps to slow the fundamental issues like The Tendency for the Rate of Profit to Fall, or fundamental exploitation.
Fair enough. But also, fire fundamentally spreads uncontrollably to the point where it destroys everything; that's it's nature. That doesn't mean it's a bad idea to heat your home.
I get what you're saying and I think we're pretty much in agreement on the facts; how to assign the labels isn't to me a critical back-and-forth to have. I get what you mean. I guess my big substantive question would be, what would be examples of society where your vision of leftism has been implemented? When I talk about capitalism being a useful tool, I mean that I like having vaccines, supermarkets, computers, all the stuff that's the the fruit of having a massive organized economy. Obviously the current system isn't the only one imaginable that can produce that stuff, but I think if you're going to point to the problems of the dystopian US economy (which are very real) and argue for throwing the whole thing away, what are you going to replace it with? A semi-command economy like China, or libertarian everyone-do-whatever-they-want-with-their-business system, or back to individual farming, or what? Like where is a society that has implemented what you're talking about wanting to do and how has it worked out?
