The biggest reason anyone would not support a gold standard is because of the limitations it imposes on growth in the money supply and balance of payments. Simply put the gold standard broke down. As far as Friedmans monetarist views, they are simplistic at best and do not account for many economic variables that WILL assert themselves despite a well managed growth of the money supply. Right now, despite certain built in systems, we have probably the best test yet of his theories. Greenspan did his monetarist duties well and it looks like Bernanke is a team player. The Bush Administration ( like most conservatives) doesn't have a clue about how to effectively manage Fiscal Policy. So, will an effectively managed growth rate in the money supply overcome all economic ills? I happen to believe that it is a good start, but unlike Friedman, I feel that as the system acclimates itself around an economy that is dependant on monetary policy it will develop new ways to force the hands of monetary policymakers and force them to abandon the flat line policies. My thoughts right now are that inflationary fears will wind up (if they havent already) forcing them to take measures which will restrict monetary growth and that the ways the economy has adapted itself will implode. The result being a deflationary cycle of epic proportions. I also believe this could be ( could have been) avoided by some reasonable countercyclical Fiscal management( too late now). We need a Friedman student at the Fed and Keynes students in the White House and Congress and we might actually find a great balanced economy.
