the iphone (apple) is made in china. great product, right?
I wouldn't use Apple as a proxy for goods made in China. Apple is a vertically integrated company and they own virtually every stage of their production. It's all very tightly controlled.
There aren't any other brands made in China that benefit front this type of integration, that I'm aware of.
The quality control is just lower in China than in America. That's a fact. They also choose to go with lower quality parts in order to keep the end-consumer prices down. Another fact.
Some companies eat the cost and stand behind their product, like Griot's. Their stuff is made in China but they're taking all the risk with a Lifetime Warranty. Contrast that with Rupes, their product is insanely expensive and yet you only get 1 year? Hmm...
