Capitalism isn’t necessary; a new economic system that takes some aspects of capitalism is necessary. If you have to strip capitalism of all of its core features to make it work, you’re no longer dealing with capitalism but rather a different economic model.
I agree. People who say, "nuhuh, capitalism works!" are 99% of the time thinking of the basic concept of markets or money. Which ... Very specifically, are NOT capitalism.
They are used (and abused) by capitalists, but they are not inventions of capitalists.
So what’s the difference between capitalism and markets? I would have thought the freer the market the more capitalistic it was, not so much that there’s a separation of the two.
Kind of. The market can have Capitalist entities and Socialist entities, but the market itself isn't Capitalist.
Not necessarily. Co-operatives are more difficult to start in a predominantly Capitalist system, and Capitalist entities usually can exploit their workers more in order to gain temporary competitive advantage. I don't believe this is sufficient reasoning to value Capitalism over Socialist entities.
I'm not a Market Socialist, for clarification, as I do think there are issues. However, Capitalism isn't markets.
