Lots of countries have explicitely recognized that putting control of the money in the hands of public-minded government is often horrible idea. Those countries created separate institutions that are responsible only for keeping value of money stable by regulating its supply. They don't care about what public or government wants. They don't care what effects on the economy will their decissions have. They just have to keep inflation around 2-3% by adjusting rates.
USA money controller for some reason has to support the economy with their decissions. The only reason they get away with it without hiperinflation so far is because dollar is strongly tied to the oil and because USA after the WWII had thriving economy, not economical wasteland like almost all other countries that took part in the war.
