Total net liabilities (including off-balance sheets such as social security, pension and health liabilities) of the U.S. and the E.U. add up to "$135 trillion"

"...The outlook goes from murky to unbelievably grim, if one includes off-balance sheet items such as social security, pension and health liabilities, which have been promised to us over the years by well meaning but financially inept governments.

As Societe Generale's Dylan Grice puts it:

"I don't see how our governments can pay these liabilities. EU and US net liabilities add up to around $135 trillion alone. That is four times the capitalization of Datastream's World equity index of about $36 trillion, and forty times the cost of the 2008 financial crisis."

I also note that Greece, not included in the chart, stands at 875% debt-to-GDP when including off-balance sheet items!..."
