Any "fixing" of gold which is not in the hand of the free market will fail one way or another, IMTO. Who says that 3% annualized rate is the optimum, in the late 90' the economy had growth spurts in excess of 3%. That 3% (or any other "preferred growth rate) is simply no knowable, just as the unemployment under 6% was supposed to bring inflation and it never did, and now the country is clamoring for the good old days when it was at 4% and without any inflation.
