When you buy products from another country that money leaves the country and the product stays. The equation is even.
When you buy products from our country both the money and wealth stay. This helps grow our economy as the physical item is still here (wealth) and the money goes on to be spent within our economy elsewhere.
Neither the division of labor or subjective value can be used to support one view or the other as they can be applied within our own market economy or world wide.
I believe this is why the comment was downvoted, although it is at +3 now. It's not that it wasn't valid but that it didn't address the deeper issues involved. We need to take a complete, and critical look at the consequences of shortsightedly assuming getting the best product for your money is the only concern.
