I think you have a case of foreshortened historical perspective here. 1980 is not actually that long ago. And there is plenty of cause/effect visible: the debt problem led to Plaza, 1987 and the Nikkei taking the strain of global reflation, which led to the end-run and final blow-off of Asian untrammelled Confucian cronyism which led to the latest Station on Capital's Calvary...
Only alchemists believe in perpetual motion.
Those of us for who the past two years here and elsewhere have been predicting what even the blindest economist can now see, have some cause for feeling smug today.
But this is only the beginning. There is a long LONG way yet to fall. We live in interesting times after all, as it turns out.
