Here's an interesting question.
The world is awash in money. There's so much money available that interest rates are nearly zero. On top of that, the Fed is printing money furiously to very little effect.
You would think that with nearly free money available, inflation would be soaring...
So, why don't we see much inflation?
NOTE: Some folks maintain that the real inflation rate is very high, much higher than gov't figures, but that doesn't pass the smell test. For example, inflation isn't much of a factor in our everyday lives -- typically, it's just the opposite.
One reason this financial excess isn't causing rampant inflation is that it is flowing into the hands of a ever smaller number of people, and those people don't (can't) spend enough of it to inflate prices of everyday items.
IF this is true, and given the rate at which income and wealth is continuing to concentrate, almost any amount of expansion could be possible.
