Okay, let's look at history. Since about 3800 B.C. there have been something like 500 economic cycles.
499 of them have ended in a financial crisis. Most in minor debt crises, a few in larger events (like 1929 or 2008).
This one will end just like all others. There will be a financial crisis to end it.
I mean, this has been happening for so long the Bible talks about it. Trust me, trust economists, or trust the lord: it will happen.
There is another pattern. Crises, from one to the next, tend to get worse and worse until they cause really large scale collapses. The Roman Empire encountered worse and worse financial crises until finally the republic was destroyed by the empire, and eventually because the provinces broke away. The 1929 crisis ... perhaps this is a bit simplifying, but not really ... caused WWII.
On the other hand, the 1979-1982 crisis was pretty severe and yes was followed by a large expansion and a mild, at worst, crisis ended that one.
But this is not a stretch at all:
1) economic expansion (in China, the US, and elsewhere) WILL end (100% chance). And it will end soon (China, and the world for that matter, are in one of the longest continuous economic expansions in the history of the world. Meaning right now it's already very exceptionally long, if not THE longest)
2) it will restart. Maybe it'll take a war, maybe (1 in 100 chance at worst) even collapse. But it will restart. Now that's easy to see, but 1 year into the crisis that will inevitably occur that's not going to be so easy to see.
