Could it have been the other way around, where the rise of finance industries caused the "greed is good" 80s? I've assume that Nixon taking the U.S. off the gold standard precipitated the growth in the finance industry, the government needs banks to grow money supply and debt, right? "Greed is good" may have just been an add campaign designed to justify what was already happening, a frenzy of finance, consumerism, and debt that has not stopped yet.
