Today, the entire global financial system resembles a colossal spiral of debt.  Just about all economic activity involves the flow of credit in some way, and so the only way to have "economic growth" is to introduce even more debt into the system.  When the system started to fail back in 2008, global authorities responded by pumping this debt spiral back up and getting it to spin even faster than ever.  If you can believe it, the total amount of global debt has risen by $35 trillion since the last crisis.  Unfortunately, any system based on debt is going to break down eventually, and there are signs that it is starting to happen once again.  For example, just a few days ago the IMF warned regulators to prepare for a global "liquidity shock".  And on Friday, Chinese authorities announced a ban on certain types of financing for margin trades on over-the-counter stocks, and we learned that preparations are being made behind the scenes in Europe for a Greek debt default and a Greek exit from the eurozone.
