I absolutely do not think that Spydercos are overpriced, and all of this talk of "Well, why can't the models made in Taichung be made here instead??" is easily answered as "Because then no one would buy them."
It's best to remember the reasons why American companies move operations overseas in the first place. It's also best to keep simple economics in mind. Here are a few facts as I understand them after entirely too many business development/Economics/Finance courses:
1. Companies exist to make a profit, and to provide value to that company's shareholders/owners.
1a. Companies do NOT exist to provide Americans with jobs, or to make Americans feel good about their product. Those that might claim they do, are doing so for marketing or "goodwill" purposes. People generally do not want to hear harsh truths, and will hate you for it, which is why companies do not advertise this fact.
1b. If a company could produce or provide its goods or services with fewer workers, it would (as usually evidenced by people being laid off when need/desire for that company's products reduces). Any other view makes no economic sense.
1c. The taxes a company pays for being in business in America are exponentially higher than most other countries.
2. Companies generally move production overseas because at the end of the day, they have to balance the numbers between debits and credits. American workers are expensive, workers in many other countries are not. It's that simple. It's not about what Americans think they deserve, it's simple mathematics. American workers cost more, so you have to charge more in order to pay your workers, insure your workers, provide medical for your workers, etc. AND turn a profit. When you have an item that has a general cost in the marketplace, and making it domestically would force you to charge a price that's entirely outside of the bell curve for it, then it does not make sense to waste money, time, and resources on doing so. You open a plant in another country, and bring the costs of making the product into line with your company's requirement/desire to turn a profit.
3. (and this is the most important) The desire to make a profit isn't a bad thing.
That's why companies produce products in other countries and don't maintain a 100% manufacturing base here.
Also, another thing to keep in mind. One of the commonly stated sentiments here is "I would totally pay more for (insert imported knife here) if it were produced here!!!!". Well, that's great, but here's the thing. For every member of this board who's super gung-ho and would do that? There are ten or twenty non-Board-member casual knife-buyers in the marketplace who absolutely wouldn't. We are actually a small percentage of the knife-buying public in this country. Never doubt it.
And finally, in the interest of clear disclosure: one of my absolute favorite knives out of aaaalllll the knives in my not-inconsiderable collection is my Spyderco Gayle Bradley. I got it for $130 shipped from That Auction Site, and it is perfect (to me) in every way. Amazing super steel, amazing fit and finish, and that price, fantastic. Made in Taiwan? Wasn't even an issue in my mind.
