The Wonderful One-Hoss Shay

"Have you heard of the wonderful one-hoss shay,
That was built in such a logical way
It ran a hundred years to a day,
And then of a sudden it — ah, but stay,
I’ll tell you what happened without delay,
Scaring the parson into fits,
Frightening people out of their wits, –
Have you ever heard of that, I say?
...
...
What do you think the parson found,
When he got up and stared around?
The poor old chaise in a heap or mound,
As if it had been to the mill and ground!
You see, of course, if you’re not a dunce,
How it went to pieces all at once, –
All at once, and nothing first, –
Just as bubbles do when they burst.
End of the wonderful one-hoss shay.
Logic is logic. That’s all I say."

That is our financial system.  We believe that it is IMPOSSIBLE for the US Treasury or Federal Reserve to ever default.  The US dollar is invincible - it will never fail.  Until the day when it all collapses at once.  But that is inconceivable.  Which makes the day it inevitably collapses a much worse event then it otherwise would be.  But can we kick the can down the road for the next 50 years? If so, then it's not our problem.
