For many companies, not doing so is corporate suicide. Apple's earnings spiked right after it moved its Mac assembly lines to China. It has stopped assembling its products stateside. If your logo is on the end product, the trick is to conduct random audits without forewarning. But that's true even if you're manufacturing stateside. Some manufacturers went overboard in their cost-cutting, perhaps figuring that they could cut back on both auditing and labor costs. The ones that did not have had few issues. Dell assembled PC's from Chinese-made parts at inception, but gradually moved all assembly to China while becoming the biggest PC maker in the world.
Bull crap. Apple would still be making billions if all of it's manufacturing were performed in the USA. The amount of labor per phone is about 16 dollars. if made in the USA it would be 4x times that or 64 dollars. That is 64 dollars on a 800 dollar phone.
Apple Inc earned gross margins of 49 to 58 percent on its U.S. iPhone sales between April 2010 and the end of March 2012.
