Can you describe one that is better?
Whenever we tried something else in the last 150 years it created a living hell for nearly everyone who was lucky enough to survive. And what we had before that was not paradise either, far away from it.
The problem is not capitalism but unchecked, uncontrolled capitalism.
People where mostly growing food for themselves and their family, not for each other. This changed when the first basic forms of capitalism where invented, things like markets, guilds, and skyrocketed with industrialization.
No other system that we tried ever worked as good and produced so much peace and prosperity like capitalism. Is it perfect? Fuck no! Nothing that involves humans could ever be. But it is the best we have from a bunch of broken and fucked up systems.
Yes, but there is no easy way back to that.
The world, the western/first world at least, would collaps and Fall Info complete Chaos and dispair should electronic payment ever gets unusable. Everything depends on it, without it we would fall back into small, localised markets and nearly nothing would be prepared for that. Food production would collapse, machines could not be repaired because no repair parts could be created or delivered, the power grid would break and so much more. It would be apocalyptic, and so many people would die or suffer
And what we have now is still leagues better then what they had in 1726.
