Right you are. When I got out of the Air Force, I went back to school to get an MBA and in one of my classes, I heard a bout a guy who wrote a master's thesis named something like, "The Big Mac Link". He tied almost everything over a 40 year period to the price of the Big Mac. Over the years, a big mac has gone from, what, 39 cents to about $4. Lots of other things had price increases that closely mirrored the Big Mac.
