Stage 4 and 5 are considered unrelated to 1,2 and 3 by historiasn. In World war II, after the spanish civil war, or after the crack.. there was no rioting, no turmoil. actually,t he worst turmoil always happens when 1 2 and 3 are not present.

I guess 1 ,2 and 3 can be mroe realted but I would not be so sure.

In any case, I doubt there will be any collapse of American economy. I for sure hope of zero growth for the US four half a decade (long but not deep depression) so as to rebalance the world economy, produce a multipolar world and address the global isssue of global warming  and lack of sanitation (yes, you read right lack of sanitation is killing mroe people thant he present worst case scenario of global warming...thoguh the worst case scenario fro gobal warming can be updated), and generate the politcial changes that the US need to become a respected member of the world again.

A pleasure

I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact. Levi-Strauss, Claude
