This puts you in a awkward positon, siding with the South and their anti tariff position. If you want to see a service/agicultural society that imports all durable goods, and are in favor of that, then look no further than the CSA.
I do understand the ironies here, and am happy to point them out.
My position is that global trade with our close friends and allies is a good thing so long as we do not become overly dependent, and they do not take unfair advantage of us.
So, free trade must also be fair trade, and trade with our enemies can be very destructive, the more so as we become dependent on them.
