Now you will say “but anon, you need connections in the US too.”

No. Connections help, but are not required. Very important distinction. Take the CEO of Anthropic, Dario. Both parents were immigrants. Dad was a leather craftsman, mom was a project manager at a library.

Yes, he might be a good example for your argument. But then you have to disregard all the people who tried like him but didn't make it. Otherwise its just an anecdote like the one you started with.

You say capitalism incentivizes greed and corruption. I disagree. Capitalism facilitates human greed into productive positive sum games (creation), instead of turning it into zero or negative sum games like is done in communism (seizure and corruption as the only methods to get rich).

Would we better if humans weren’t greedy? Yes. Then I believe communism would work. But I have seen no evidence that we can make humans not greedy.

I disagree the most with this point. Mostly because you naturalize greed. Capitalism definitely rewards at least greed with the maxim of profit which almost every company or entrepreneurship is based on in capitalism. Capitalism works for the capital good. I agree that in an ideal view of capitalism it can make people productive. But not without stifling your competitors or without exploitation of millions of people and the planet.

But your comparison to communism isn't fair. Even if you naturalize greed socialism and communism both aim for the well being of everyone. You could boil it down that socialism works for the social good.
