I'm talking about the post-World War II economic expansion seen in USA, aka "the golden age of capitalism."
You mean when the tax rates on the wealthy were very high?
You're arguing that the economic expansion was a result of taxing the wealthy? Or, are you saying that because there are ways that this wasn't "the one true capitalism," then that means my whole point is invalid?
Well, I'm still not sure what your point was. I think you were arguing that America's prosperity was due to the invisible hand. I'd argue it was the government creating industries such as infrastructure projects and war.
