Yet, US manufacturing output and US industrial production have not recovered to their pre-contraction high.

So what is driving the real GDP growth? In my opinion, the rise in real GDP is an illusion produced by the under-measurement of inflation.

As I have reported on many occasions, John Williams of shadowstats.com has concluded that changes in the way that the government approaches the measurement of inflation has, in effect, defined inflation away.

Formerly, if a price of an item in an inflation measure rose, the inflation rate would rise by the price times the weight of the item in the index. Today, if a price of an item in an inflation measure rises, that item is removed from the index, and a lower cost item substituted in its place.
