I think there's a relationship between the two. It's called multinational corporation exploitation. We're all 'rich' because of that, not because we have some sort of better system. The planet is totally interrelated economically. Just pick any random rich capitalist, and search on his/her portfolio. That t-shirt you bought today was most likely made by cheap labour in some foreign third world country.
Believe it or not everything that happens in other countries is not the fault of the US. There have been people in the rest of the world longer than in the US. American's work harder than anyone else. We created our wealth, the first Europeans that came to the US didn't steal gold from Great Britain.
There are good things about capitalism and there are bad things about it. But, overall, I think it is a better system because it rewards creativity while socialism stifles it.
Now, I do think that coorporations go too far and pay their CEO's way, way, way too much but I don't make the rules.
The t-shirts I own are made by cheap labor in some foreign country? Of course they are. What's wrong with that? Are you suggesting we shouldn't provide them with jobs? I don't know anyone forcing the Chinese to move to the cities and sit at sewing machines all day long. They can stay in the country and work their fields if they want.
You think American's never worked hard, all the cities and infrastructure and economy just built themselves?
