How Long Can You Maintain A Sugar Rush?

I'm having loads of fun with Fred.

Things seem to be getting better.


But isn't it because the government is injecting massive doses of borrowed money into the economy?


And because the Fed is lending money at 0%?


You can't borrow and print forever. Are we using this temporary respite to reduce debt?


Doesn't it look like a massive sugar rush? How long before the sugar no longer produces the euphoric high?
