We are definitely in the year 2000 in this cycle [0] and between now and somewhere in 2030, a crash is incoming.
Let's see how creative the banks will get to attempt to escape this conundrum. But until then...
Probably nothing.
They don't need to get creative, they just need to buy congress or the administration. Same as they've done every time things get messy.
And you know what? It works every time.
The question is "How long can they keep extracting money before the economy implodes?"
The people producing macroeconomic indicators in the US were fired about 6 months ago for putting out an honest report. Since then there's been very little correlation between public sentiment on the economy and the official indicators.
So, we're definitely in some sort of overhang situation, where the economy is imploding, but the stock market goes up. I think that's unprecedented in the US. In developing countries, when this happens, it usually leads to things like hyperinflation.
So, I guess the real questions are: "How do you short the dollar?", and "How can you tell when the banks start doing it?" so you know when to jump off the merry-go-round.
