I understand that we should consider the human cost in this sense, but if you're going to appeal to the empathy I have for the people who lose jobs, you can't ignore the people which benefit from the "industries being sent overseas" by receiving those jobs. Of course I'm sad when I see a homeless person in the US, and yes some of them are homeless because their jobs "moved overseas", but those jobs might have helped a few really poor Chinese farmers attain a higher standard of living as factory workers. How do we account for that?
