I can sympathize with the protectionist mindset and it's been going on since the country was founded (New England almost seceded over similar issues). To protect some American businesses we often end up hurting other American businesses and making our products less competitive. Nonetheless that doesn't take the sting out of losing your job because the factory moved and I can imagine the pain is just as severe whether the factory moved to a sun-belt state or to a foreign country.
Dealing with the unfortunate is always difficult. We want to help the needy and what happens is the needy often blame us and try to attack us. Of course that sad fact of life will never stop us from doing what's right, just like we're not held back by the fact that when we were in need nobody helped us.
The key here is not to stew on the misery but to be ever grateful that we are well off and we're able to help others. A good sense of humor helps too...
