It is not unusual for quality to degrade over time, even (or perhaps particularly) for domestic products. The first units are built by the best engineers and technicians, who developed the product. Later units are put together "by hippies and grandmothers" (to quote a very wise chief engineer that I worked with). The engineers and the best technicians have moved on to develop the next product.
Also, people in third world countries sometimes have practical skills which we Americans lack. Case in point is the assembly of small mechanisms by Hispanic women. They have small hands and fingers, and can do work that would drive a red-blooded American crazy.
