Nostradamus was not an Economist, but he could have been---Inflation is a Self-fulfilling Prophecy...

Inflation is not a problem in the US...now.  The question amongst economists is what is the root cause of current inflationary trends around the world.  Is it demand driven because of scarcity of resources?

Or is it "too much money chasing too few goods", the classic explanation of inflation?  My opinion is it is a combination of the first and second reasons, with the first one taking precedent.  I have read too many articles lately about the world-wide demand for resources to not give it credence.  Here is another one excerpted below.
