I think the point here is that the Chinese stuff has to meet Snap-on specifications and quality control; the same supplier could be making the unusable junk available elsewhere for the vendors that have no standards.
The Chinese are perfectly capable of making good stuff, but we have generally taught them that Americans will buy anything, then buy another of the same when the first one breaks...they pretty clearly see no point in watching over quality unless they have to to get a contract. Go around the quality control, and you're back at K-Mart.
