Last night I watched back-to-back episodes of "Castle", the popular crime series.
It was a two-parter, with a plot revolving around a series of events that, if touched-off, would result in the economic collapse of the U.S.
It turned out that the triggering event was a death of Chinese child who was the daughter of an influential Chinese businessman, and the death would be tied to the CIA. That, in turn, would lead to the Chinese ceasing to buy U.S. government debt, leading to austerity measures, leading to tax riots, etc. etc. and eventual collapse of America.
It is interesting that Hollywood scriptwriters can foresee this, but our rulers apparently can't.
