Your conclusion is so far off. Germany benefited big time from EURO because other less productive countries can't compete with Germany by depreciating their currency. This was one reason that Greece has accumulated bigger and bigger deficit.
That's a good thing. The ordinary workers have been exploited for too long in China. It's high time for some change. What's the point for the hard work if it only brings food and shelter to the workers themselves but finances Americans big screen TVs and all the gadgets? China will never become a big power if it stays on the lowest level the the food chain forever.
There is no parallel between today's Germany and Japan of 20 years ago. On the other hand, US is more and more like old Japan. Germany hasn't had any serious bubbles. On the contrary, US this time and Japan back then both had a huge real estate bubble. Japan also had huge bubbles of its stock market.
Japan also implemented credit easing in a big way and resulted in huge deficit. Another similarity between US and Japan.
In one word, it's US that becomes more and more like Japan of the 1990s.
