Giving control of the specie to private banks was a gigantic mistake.
Except of course, if you're an adherent to the theory that private bankers are more interested in the good health of commonweal than a representatative form of goverment.
I think this latest economic depression put the lie to the above theory rather nicely, though, does it not?
OTOH, there is absolutely no reason for any of us to expect that sooner or later the insiders of government aren't likely to also become parasites on the commonweal, either.
In fact, most cases of inflation stem from governments (or Kings) debasing the specie.
I suspect that statistic mostly has to do with the much longer history of monarchies controlling currency than representative forms of government.
The bottom line is power corrupts regardless of who has it, folks.
The powerful (in government OR the private sector) inevitably abuse their power for their own benefit.
