The US population increase alone since the late '60s would require about a 60% increase in output, and that doesn't even include more consumption per capita and all the new products that didn't exist then.

That also assumes -- incorrectly -- that the consumption per capita of all these new products would be higher without imports. I don't think that's the case at all.

No, it does not assume what you say it assumes at all. The population increase is a stand alone factor. Then there are other factors such as new products and increased consumption and manufactured products per capita.
