I don't think getting booed off the stage is a good way to end the discussion. The US is already a major exporter, of the goods we have an advantage at producing: simple foods, refined oil, advanced machines. Forcing farmers to plant avocados in potato fields isn't really going to help anybody, and neither is transferring oil refinery engineers to working on optimizing garmet factories. This will all take place against a backdrop of a poorer world with fewer dollars to spend on our goods, so it won't help our export sales either. Europe and China need to earn the dollars they buy our wheat with somehow - and without buying from them, I don't see how they'll do it.
