Um, you guys know better than this. Or should.
What was the inflation and unemployment rates at the start of that chart in 1973? 6.2% and 4.8% What was it in 1974? 11.0% and 5.5% What happened in those two years? The oil embargo during the 1973 Arab-Israeli war.
So, we had nearly full employment and fairly high inflation, then a quadrupling of oil prices (~$3 to ~$12 a barrel) in less than 2 years. Unemployment went up, and inflation increased from a fairly high level to an higher level. Unemployment increased because of the recession.
What happened in 1979? The Iranian Revolution and the Iraq-Iran war and another near tripling of oil prices (~$14/bbl to ~$40/bbl) - http://en.wikipedia....logy-june2007.gif .
This doesn't contradict anything I posted.
Has oil tripled or quadrupled in the last 2 years? Not exactly. Oil is down substantially from its peak ($145.31 on 7/3/2008) but up substantially from its recent low ($30.28 on 12/23/2008) - http://tonto.eia.doe...?n=PET&s=RWTC&f=D (What happened between July and December 2008? The world economy imploded.)
At the moment oil's at $104.34 (on 3/30/2011) - lower than it was less than 3 years ago. If oil's tripling since December 2008 were driving US inflation, then the 12-month CPI would be a lot higher than 2.1% - http://www.bls.gov/n...lease/cpi.nr0.htm . (The 12-month CPI in July 2008 was 5.6%.) Things are different now compared to the 1970s.
Are we at nearly full employment? No.
Do employees have strong labor contracts with automatic cost-of-living increases that will feed price shocks back into inflationary expectations? No.
Is US Capacity Utilization around 85% as it was in September 1973? No. Is it above 81% as it was in December 1980? No. It's 77% - a very low level.

The lessons from the 1970s tell us that we don't have to worry about inflation now. The economy is too weak for inflation to take hold.
HTH.
