According to BEA data, the U.S. economy has increasingly become more and more of a service economy (see top chart above).  In the early 1950s, less than half of the national output took place in the private services-producing sector of the economy, and more than 40% in the private goods-producing sector.  Now more than 2 out of every three dollars of GDP is produced by private service industries in the U.S. (legal, financial, management, administrative, technical, scientific, publishing, information technology, etc.), and the share of value added by private goods-producing industries has fallen to 17.7%, or less than half its share fifty years ago.  
CNBC reported last week:
"The annual change in prices for data processing, recreation, lodging,  medical services and tuition are all showing a downward trend,  according to David Rosenberg’s analysis of the government’s CPI data.
With all the hubbub about $100  oil, surging food prices, along with the comparisons to the 1970s, Rosenberg,  who is chief economist and strategist at Gluskin Sheff, is trying to make the  point that the U.S. is now primarily a service economy, with these industries  accounting for much of our employment and two-thirds of our spending (see top chart above).
“Service sector inflation is now  running at historical lows of little more than one percent, and here we are  about to enter the third year of a statistical economic recovery,” said  Rosenberg, formerly the economist at Merrill Lynch where he made his name by  going against the perma-bullish Wall Street crowd (see bottom chart above). “Service sector inflation  used to be sticky, because this area of the economy years ago was dominated by  unions, was protected by entry barriers, and did not face much in the way of  competitive pressures. The times have changed,” wrote  Rosenberg in a note to clients Tuesday.
“Commodity-based economies have a  serious inflation problem because food and energy are so crucial to that  smokestack, low-income model,” said Steve Cortes of Veracruz LLC. “But in a  services-based economy like the U.S., many areas are outright deflating, like  technology — and many more key areas churning sideways: professional services,  brokerage of all kinds, hotels.  Inflationary periods like the 1970s start with  wage inflation, which is sorely missing from this recovery.” 
Indeed, Rosenberg found there is  an 88 percent correlation between wages and inflation —and wages today, adjusted  for productivity gains, are declining on an annual basis. Don’t look for that to  change any time soon with unemployment still above 8 percent. Maybe that’s why  the Federal Reserve says it has a dual mandate of stable prices and full  employment."
MP: I've made some of these same points before.  In the inflationary 1970s, almost every measure of prices was increasing: food, energy, core inflation, wages, services, interest rates, etc.  We now have a wide mix of inflationary, deflationary and flat inflationary forces, along with decelerating wage increases and low interest rates, and that's not a formula that results in overall inflationary pressures.  At least not yet.  And since inflation for services has been below 2% for almost two years now, there's not inflationary pressure there.
