A good example is the business I'm in - we started out with web and application coding in California. Well paying jobs they were - also a huge expense to the company. C level was under pressure to cut costs so moved the web to Canada and the coding to China and Singapore. Definitely resulted in a huge drop in quality...but not enough to drive customers away - they just have lowered expectations now.
That seems to be the mood of the American consumer - go with the cheapest stuff and just put up with the low quality.
After all, who would buy an American-made toaster for $40 that would last for 50 years when you can get a $15 toaster at Walmart that will last for 2 years if you're lucky?
