What do you think we should replace it with? Some years back, when my country replaced a corrupt, entrenched coalition govt of 60+ years, the winning party sort of looked around and said: ‘uh… huh, OK, we won. We werent expecting to win. Now what? We have no plan. Lolz?’
In that light, what do you think should replace the big C, and how do we ensure human nature doesnt juat exploit it for a few individuals benefit?
problem is OP you don’t just bring down/destroy/disappear capitalism
capitalism is an umbrella term for the economic system that emerged from the most basic early trade/money systems/financialisation
so in reality you start with capitalism and change it to enable things you like
anyone that doesn’t start answering your question with capitalism is a bullshit fantasist
judging by the other replies you’ve had that’s what you got. that’s why these transition plans to communism are so threadbare and disfunctional. they are just hand-wavey dreams
