However as someone who spent years in / around manufacturing, I can assure you that, all things being equal, the probability of having lower QC and subsequent quality issues is much higher in China than in Japan.
We aren't talking about Japan vs. China. We are talking about a lens made in Taiwan vs. a lens made in Japan.
i think the problem is cost. look at how much stuff used to be made in America. all these companies look at how much something costs to build. "building it in America costs XXXX number of dollars, but if we get the items manufactured in another country, that means more profit."
This is not only about profit for the companies, but also to see who can produce quality goods at the lowest possible price.
HONESTLY, if Canon produced the same lens in the US and Taiwan and charged what it actually cost them to build the lens, who here would be willing to pay the extra cash for a "US made" lens? Keep in mind, we probably aren't talking about a few bucks, but probably in the hundreds of dollars for THE SAME LENS.

??! The time of made in
