Yes, I agree, there's always economic inequality, what I was trying to say was something like "without capitalism, we wouldn't be living in a world where some people make 10 million times as much money as other people." (Maybe I should edit my post accordingly?)

Yes. But there's also another reason for this that you don't touch on: Large scale inequality requires large scale success. If the only thing to go around is a 1000 chickens, then no one is ever going to have millions more of anything than anyone else does. You can only have things where people have such stark contrasts in wealth and resources when large quantities of wealth exist.
