I think those signs in todays economy work only if the consumer has money to burn or if the consumer has determined in his mind he will not buy foreign products and be limited by what is available in the USA. I read a posting over at Audio Asylum where one consumer said he buys Rogue because its American, and its about at his budget of $2000. He said he refuses to buy gear from China and will not spend more than 2K He also knew his choice in audio was limited as well.

But the point of why China....its because of the greed of the American manufacturer. From the parts to marketing to the finished product....its just all to expensive, so they go to China or other places where for the same parts and a finished product, they pocket more of the profits....who can blame them?
