I'll stay out of the other aspects of the pissing match, but will counter at least part of this. Personally, I have no jingoistic tendencies, nor do I think that countries other than those outside of the US and EU are not capable of quality. There are craftsmen/women in every country around the world that, given the right training and materials, could turn out a spectacular instrument. And at this point, there are some very experienced luthiers in those countries since they've now been doing this for awhile. In general Asian countries have a history of taking US/EU products and figuring out how to do it more cheaply/efficiently, usually by lower labor costs, and sometimes with questionable QC - that can be traced back to a combination of a lack of experience along with building to a price point.
Every builder makes their bass to a price point. And businessmen have that as their primary metric. In a case like this, building is sent offshore to hit a certain margin. It may have equivalent quality to a US counterpart - and the lower build cost can increase value for the consumer. Win win - until you think about the fact that the instrument *could* have been built in the US by US labor. So that means a job opportunity was lost to overseas. The strict capitalists will argue that US legislation and labor unions are to blame, and we should get rid of that "anti-business" legislation so our labor costs can be more competitive. That is largely nonsense though. In most cases the US is just ahead of the industrial revolution curve relative to the Asian nations. China is beginning to learn the hard way about unbridled manufacturing with no environmental consideration.
I relate this to the US because that's where I live. Since I've been around for awhile, I've lived through the globalization of the past few decades and I've seen many things off-shored. To-date I have personally been largely unaffected because I'm in a creative/innovation industry and that is one area where the US still (for now) maintains a competitive advantage. But it has been devastating for large parts of the country. One can blame the people for not adapting quickly enough, but corporate greed and hubris is hard to fight.
I don't begrudge the Korean worker his paycheck. But my money doesn't have to fuel it. I'd rather it goes to as many of those in my country as possible, as a rising tide raises all boats. That isn't the least bit racist or xenophobic - it is "acting locally" and making small differences where I can. Thankfully I have the opportunity to make those choices - others are not so lucky.
