Real talk. Socialism works great for much of europe. Look into england, austria, pretty much any Scandinavian country they all have programs and systems focused on supporting workers. That they would never give up.

Second are we talking Big C or little c communism. They are different things. And you are wrong immediately off the bat. Under communism which is not defined as socialism in its entirety. No single person owns the means of production. But people do own the means of production. Under big C communism, let's call it what it is leninism. They have a warped and twisted definition of who the people are. Expanding it out to a single Nationwide party and that party's dictatorial leader. That's very different from communism. Under communism the workers own the means of production. Meaning that if you work in a factory. As a worker of the factory you own a piece of, and have a stake in the factory and its success.

If people require capitalism to motivate them to strive for more. How did we get where we are? Capitalism has only existed a few hundred years. Human history goes back tens of thousands of years. How does that work? Because it really seems like we don't need capitalism for that. And there's no evidence showing that communism hinders it either. You do realize that even under the warped leninism that the Soviets used. They industrialized, expanded, had scientific and technological progress alongside the rest of the world. That doesn't excuse the atrocities that they committed or the capitalists have committed. But that sure doesn't seem like it puts a damper on striving for more etc.

And if human nature is the biggest roadblock to socialism as you say it is. It's just as big or bigger a roadblock to capitalism. Your argument against socialism is more of an argument against capitalism. Think about that. I think you mean well. But I also think you have very little idea about what you're talking about. Which isn't an insult. When it comes to some Western Nations and especially the united states. We are washed in propaganda and purposefully miseducated.
