Difference in quality in products made in China?

There is a belief among many audiophiles that electronics assembled in China or Korea are not as well made as products assembled in the USA and England. This has nothing to do,(I believe) with the "technical abilities" of workers, as it has to do with standards of quality control, and the sourcing of less quality parts throughout Asia

This may be all hogwash and just biased opinion, but this question comes up to often to be quickly dismissed. From my own experience which is limited compared to other members, the products(amps. pre-amps CD players) I have owned that were made in the USA, or UK, and Canada, have been solid in terms of long term reliability. I would like to hear others opinions on this issue.
