Inflation is coming – The Fed has increased money supply from $800 Billion in 2007 to over $3.9 Trillion in 2013, and it's still rising. Any responsible economist will tell you that an increase in the Money Supply is highly inflationary. Generally, a quadrupling of the Money Supply will eventually lead to nearly a quadrupling of prices after a lag that could range up to several years. As the value of the Dollar declines, foreign countries will stop using the Dollar as a 'Reserve Currency' to purchase commodities and for international trade, and when that happens, the demand for Dollars will dry up and all of those excess Dollars in circulation will translate directly into spiraling Inflation.
Few people realize that Inflation has been persistent over the last 42 years – for example, the purchasing power of a Dollar in 1970 is now only 17 cents.
