Sobering.  Q: How long can we "kick the can down the road" spending "money" we don't have on a worldwide trillion-dollar empire of military bases abroad, and a spiralling ponzi-scheme of entitlements at home, desperately begging and borrowing from China (and whoever else will buy our increasingly risky debt) and printing money out of thin air to "pay" for it all?  A: Until the road ends.
