As far as leaders who get in power go, they can't get more fiscally conservative than Gaddafi. Shocker.

The value of any currency is tied to perception of future events. Value is complex and dependent on more than just productive capacity. For example the most valuable objects often have no practical use. The same is true of earning capacity where entertainment is often more valued than productive capability. As a general rule things become less valuable when there are more of them. Currency is no exception.

The thing to keep in mind is that deflation historically has had worse consequences than inflation. There will never be a perfect currency. Attempts to regulate them will always miss the mark. It's a question of by how much.

The best way to prevent inflation is to establish and maintain a free market capitalist system of economics. See various lectures and interviews of the late great Milton Friedman.
