Only difference is that lately we've been also hearing that the EU will fail. Their failure has been only 2 or 3 years away for the past 10 to 15 years or so. As for China, ever since I was at the University of Wisconsin watching Bush the Greater lose his election to Bill Clinton, China's failure has been "imminent". Five years away, a decade at most.
Every year.
For the past 30 years.
I realize that even broken watches are right twice a day, but even that would be just a matter of luck or happenstance at this point. It wouldn't be because the doomsayers like yourself were correct about the EU or China. Or even the bullish people like yourself being right about Japan or the US. Or even the people with the opposing opinions being right. I've lived long enough now to know that if you guys get something right it's likely all down to simple happenstance.
