Comparing buying U.S. made knives and buying China made iPhones is Apples and Oranges. It's an entirely different series of circumstances when a manufacturer ships jobs overseas producing textiles or tools (industries where there is extensive manufacturing facilities in the U.S.) and a company that is in the electronics business (which has always relied on the exchange rate, expertise and labor market in Asia to produce a competetively, or even a reasonably priced product).
That kind of reasoning is a symptom of the underlying directive of modern knife manufacturers, and the reaction from fans of those manufacturers that wish to support their decisions. Nothing has really changed, there has always been knives made in the U.S. and knives made in the Orient. Since the products are so simple, material costs and availability play a factor. Selling knives made in the Pacific has traditionally been a hard sale to collectors and enthusiasts, and Spyderco has used their clout to get the idea over with lots of people. Up until a few years ago manufacturers have overwhelmingly took the stance that knives produced overseas should be made as economically as possible to target the widest audience and get in at the lowest possible price point at the expense of material quality and reputation among collectors; the current demand for pricier modern models has allowed Spyderco and others to basically create this new market, and as everyone can see there are receptive buyers. They're disregarding the basis of U.S. made vs. Indo-Pacific made though; which is the general market. In the general American market, U.S. made goods enjoy a strong reputation, and oriental goods do not. Only an informed collector would even know that there are Asian manufacturers that are aiming to meet American quality standards and using materials that are of a higher quality. If knives were strictly a functional item then we would all own 1, but they are as much a collectible or an heirloom, so that plays into the market as well; until Asia as a whole reaches parity with western Europe and the U.S. in terms of overall quality, the sentimental aspect of U.S. quality will always make those knives more desirable in general for the average Joe or your grandson, and that means they're more desirable to us (because you want to leave your Grandson a knife he likes, and not Asian junk - and as an investment the home grown piece will retain its value better). Remember, they don't know Taichung quality, but they do know that knives made in Asia are junk (whether it's ignorant or true, or false, they know it).
The best way you can support the combination market (US quality and material and Indo-Pacific labor) is by continuing to buy them. Insinuating that other collectors are racist because they prefer American made knives is a terrible way to show support for those products because there are reasons why American made products are more desirable, even if those buyers can't convey those reasons. It often sounds like the biggest proponents of Taichung knives are trying to convince themselves more than anything. If you like them, buy them. Keep in mind though that you adopted your view of those knives earlier than the market, and that when you leave your collection to your son there is a chance that he sells them for a fraction of the amount he would have sold American made knives because even though that sentiment isn't always true, it's very real and there is a value to it. Spyderco enjoys that value as well with their Golden stamp, so they're really getting the best of both worlds as long as buyers still consider them primarily an American company.
