Via Naked Capitalism, a fascinating interview with economic anthropologist David Graeber about the history of debt over the last 5,000 years (and the oft-intertwined history of slavery):
Since antiquity the worst-case scenario that everyone felt would lead to total social breakdown was a major debt crisis; ordinary people would become so indebted to the top one or two percent of the population that they would start selling family members into slavery, or eventually, even themselves.
Well, what happened this time around? Instead of creating some sort of overarching institution to protect debtors, they create these grandiose, world-scale institutions like the IMF or S&P to protect creditors. They essentially declare (in defiance of all traditional economic logic) that no debtor should ever be allowed to default. Needless to say the result is catastrophic. We are experiencing something that to me, at least, looks exactly like what the ancients were most afraid of: a population of debtors skating at the edge of disaster.
