"We still live in the 20th Century.  Nothing much significant has changed in our lives in the past twenty years.  Symptoms of a deeper rot are appearing here and there, foreshadowing a larger crisis, but the crisis itself has not arrived yet.  We still live in an era of Pax Americana, the old republic very much a strained and tired Empire now, with the U.S. Dollar as the world's reserve currency.

That is going to change.  

The next task for History is to dismantle the untenable structures and institutions put in place by late Modernity, which have been extended now as far as they can go.  Our debt-based monetary system will collapse, our unbacked fiats will be worthless.  The debts and unmeetable obligations will all default."
