Did going off the "gold standard" contribute to the volatile markets since the late '70's?

Channel surfing and ran across this crazy new Teen Titans.  I thought it was goofy as hell and then they started a skit on "gold".

Little did I know it but they gave a cute education on the monetary system.

I know it's slanted but do they have a point?  Did going off the "gold standard" contribute to the economic chaos we've seen since the 70's?
