It is true that many products from China have poor quality, but almost all products from US are low quality.
I guess you are trolling but....
The US has made low quality products at times as Japan has as well. In the 70's Japanese stuff really started to improve. We really did say "cheap Japanese crap" back then. In the 90's it was considered the best and in my mind recently has started to pull back in quality.
Same thing for Korean products. When the Hyundai accent came to America it was just one (big) notch ahead of the Yugo. It was junk. Now Hyundai makes some of the best cars (right here in the USA even).
I currently can not think of many products that are US made that are of low quality. In the 80's many American cars really sucked, but by the mid late nineties that started to change. Today, American made cars are pretty close in quality to foreign cars, and in many cases the variances between models are greater then the variances between brands.
