This website shows the change in the U.S. currency supply for the past century: http://www.frbatlanta.org/invoke_brochure.cfm?objectid=83FD41E6-9AF0-11D5-898400508BB89A83&method
If you look from 1950-1960, the supply of U.S. dollars increased only "slightly" compared to other decades. And guess what, the 1950's were a great decade for the economy!

At most, I think only 5% of the adult population would need to stop cooperating to have real change.
