Look at the chart of Rome's population falling from 1.4 million to 30,000.
A model you'd like to follow?
Global financial implosions are chaotic.
a) No. There has never been one, so you wouldn't know.
b) Aggregate human behaviour is chaotic.
c) Chaos theory is a
theory about the behaviour and evolution of complex dynamic systems. You seem to be confusing the general idea that things are unpredictable with different ideas of wanton destruction.
You assume too much.
And you don't seem to understand the issues.
For example: Japan owes no debt to the outside world. What the media have labelled debt there is just credit. Some countries have it bad for various reasons, for example: deregulation of the banking sector which allowed the banks to become (more) corrupt and trade among themselves, while withholding credit from the people, thus turning the GFC into a real crisis rather than just imaginary bullshit where the banks' dodgy books didn't add up.
So when you say "order is propped up by debt", you're completely wrong. If anything, credit is being propped by (relative) order.
