If you’re going to hold grudges against any given country, and boycott any products from that country, you may have a hard time sorting things out.
Example: a lot of Japanese cars are built in the USA, while a lot of American cars are built in Japan. So… is buying a Dodge Colt more or less acceptable than buying a Toyota Camry? Which is more patriotic? Which is “buying American”?
Or… what if you buy a computer that’s “Made in the USA,” but all of its components were made in China/Japan/Taiwan/Malaysia/everyplace else? How pure must a product be?
And finally, how long can we hold a grudge? How do we deal with countries that were our allies at some times and our enemies at others? Serbia is on our… manure list now, but during WW2, they were on our side. If I had a jacket made in Serbia ten years ago, should I burn it now?
I don’t mean to be dismissive of the question, because I sympathize with people who want to use their economic power. Personally, I try very hard not to buy products from CHina… but you know what? It’s extremely tough not to buy from CHina!!! Every other product out there (especially electronics) is made in China. Have I ever, out of sheer frustration and desperation, bought CHinese products? DOZENS of times!!! I tell you, ideological purity ain’t easy!
