Is the U.S. really a post-oil economy?

One way to gauge the real economy is to look at charts of the GDP, wages, household debt and the price of oil; another way is to correlate all of these on one chart. The following chart (courtesy of frequent contributor B.C.) plots these four metrics thusly: GDP/(wages/household debt)/price of oil.

As the U.S. dollar strengthens against other currencies, the phantom corporate profits generated by a devaluing dollar will vanish.
