About the U.S. Financial Burden Barometer

I've posited the US true debt burden is higher than $100 trillion.  The official national debt exceeded $16 trillion recently.  Laurence Kotlikoff says it's actually $222 trillion here.  This latest article splits the middle, declaring our financial burden at $70 trillion.  When the number of digits gets that large, does it really matter?
