unsustainable spending.

we are literally digging our own grave.

"The Obama administration's financial projections are extremely optimistic, yet even if they all come true, the U.S. debt will continue to grow unsustainably. The kind of alarm falsely placed in "global warming" would more usefully be directed towards the remarkable cooling effect this will have, as all our fiscal and demographic trends converge. For this is a predictable future; an issue where the numbers correspond to real things, not to mere speculation.

We can already see where the U.S. is headed, because Iceland and Greece are showing the way. Both have now passed a point of no return, and both are being followed down that plughole by Britain and several other European countries that will probably precede the U.S. into outright bankruptcy. The State of California also gives some clues."
