The system isn’t formed based on the wills of individuals, nor is there an inherent “nice” or “mean” quality to people. If we all decide we want to live in a perfect utopia, that still won’t take form, because that’s not how societal progression works. We live in capitalism, because capitalism emerged from preceding modes of production like feudalism. It wasn’t a choice people made, but an economic progression on the basis of private property and free-moving capital, which leads us to today where a tiny handful own the lion’s share of production.

Capitalism is riddled with contradictions, however, and these contradictions sharpen over time. We move onto socialism by organizing, where we can actually take control of production and run it along a common plan to suit the needs of the people.

Edit: figured it’s a good chance to plug my introductory Marxist-Leninist reading list, if what I said makes sense to you!
