There are commonalities among humans, but there is no such thing as ‘human nature’. Each individual’s brain creates and prunes synaptic pathways over their lifetimes based partly on their biology but also based on their interactions with society. It’s a feedback loop that helps create the people we will eventually become.
The reason you think capitalism is the only way is because you were raised in a capitalist society and therefore feel you personally need wealth to drive your motivations, I don’t. “Human nature” tends to be whatever the person saying it wants it to be. It’s also a concept that has been used to subjugate many people throughout history, such as “Black people are naturally violent, Jews are naturally greedy, and so forth.” (Not my views, just illustrating a point)
Human nature is a dangerous myth.
Re-education camps? Really?
I know it’s a hard sell, that’s why when I’m speaking more on behalf of the DSA and trying to sell our issues, I don’t bring up any of this. We tend to be more focused on what is more achievable right now, such as Green New Deal and Medicaid For All. When it comes to socialism or communism, that is something that has to be built over time through a gradual buildup of worker rights, power, and education.
We point out that no matter how equitable capitalism becomes in a country due to liberal or social democratic policies, the capitalists in charge are still exploiting the workers and the planet. I thought capitalism could be reformed for a long time, but the inherent problems with capitalism have just become worse and worse to the point where I honestly think revolution is necessary. It’s not something I want to happen, since I tend to be more of a pacifist, which is why I’m trying to solve some of the problems of capitalism through working though our broken electoral system (to the chagrin of other leftists who believe revolution now is actually possible, lol).
But I see socialism as ultimately inevitable, since capitalism as it exists today is unsustainable.
