My Back Is Broad But It's a Hurtin'

Sustainability:

The amount of debt globally has soared more than 40 percent to $100 trillion since the first signs of the financial crisis as governments borrowed to pull their economies out of recession and companies took advantage of record low interest rates, according to the Bank for International Settlements.

The $30 trillion increase from $70 trillion between mid-2007 and mid-2013 compares with a $3.86 trillion decline in the value of equities to $53.8 trillion in the same period, according to data compiled by Bloomberg. The jump in debt as measured by the Basel, Switzerland-based BIS in its quarterly review is almost twice the U.S.’s gross domestic product.

Obviously we failed to spend enough money.
