Well, if you assume that governments try to do the best for their respective economy, it may be prudent to influence the amount of money being put into circulation, it may in fact help the economy!
As long as the people trust their government to do what's best for them. But in actuality, governments don't do what's best for the people; only what's good for the government, of the people. But if the people are so willingly to be led, controlled, and governed by the government, then the government will lead, control and govern the people as they see fit, whether the people like it or not. But never assume that a government does what is best for the people, that has never been the case. A government does what's best for its own good, not the people, else that government CANNOT govern the people. Governing means to subdue the ones that are being governed, else they cannot be fully governed if the ones being governed resist the ones governing them.
Geez, how many govers did you put in that post anyways?
