You are not alone in you looking upon made in Taiwan or China (and yes, I DO know the difference!) as being "less than" the U.S.
The U.S. is somewhat insulated from the rest of the world. We are not a worldly people for the most part. (of course there are exceptions) Therefore we will have our predjudices against things made in foreign lands.
Think about it this way: China is a world superpower and is the factory of the world. Everything from cars to computer chips are made there. Taiwan has a thriving electronics industry, which means that sophisticated machining technology exists there. These are not "third world" countries, they are at the top of the world when it comes to high-tech industries.
Any more, it all comes down to which country has both the capacity AND low relative labor costs to compete. And then you have to find that exact factory with the personal the "see the difference" as Sal Glesser has said.
So, it would be a mistake to think that an Asian-made knife is of any less quality than its American-made counterparts.
Now the whole "Buy American" debate is another matter. I believe that many people may say they follow this rule, but in reality it would be very time-consuming to figure out what it means to say "American" made. Does it mean buying a GM car made in Canada? Or a Toyota made in Kentucky by Americans?
In practice we're a pragmatic society. We buy things that we perceive to be the best values, regardless of where they're made.
The consumer market covers all levels from the Wal-Mart crowd to Saks Fifth Avenue. American labor can still compete with the worldwide market, but it's usually for upscale goods. Knives fall into this category. You see the lower-end knives being made exclusively overseas. However at the mid and high-end, U.S. makers are in the mix. What has been happening in the last few years is that the Asian factories are starting to be big players here: i.e. Seki City, and now some Taiwan factories.
Maybe that's the reason for your sentiments. In time, I'm sure the perception of "Made in Taiwan" will change, just like "Made in Japan" over several decades.
