If printing money would bring prosperity, we would not be in a crisis right now.
What? Printing money hasn't worked? What if, and I know this is crazy, but what if we try printing more money?
Sure, gold backed currencies might be more fiscally responsible but would we have a society much less developed/advanced as we have today were we still stuck on the gold standard?
Which is better, to have a solvent world with half the population and technology of the 70s or today's world with defaults happening left and right?*
If we were each in charge of a world, which world would you prefer?
It sounds to me like you're making a fundamental yet very common error. You appear to be confusing "value" with "money" - and if this is done, it leads to all sorts of weirdness that looks a lot like your question.
Money is not value. It only represents value. And, as such, it's representation of value can (and should) be flexible. To quote Francisco d’Anconia, "Not an ocean of tears not all the guns in the world can transform those pieces of paper in your wallet into the bread you will need to survive tomorrow." Further, the amount of value each unit of currency represents is not fixed, and will vary with time. We are currently (in most of the world) "used to" inflation, where the value of each unit decreases as more units are printed. A century or so ago, a dollar was valued at 1/20 of an ounce of gold, so a $20 gold coin was 1oz. The economy ran just fine on this. Right now, gold is around $1200/oz, so a dollar is worth 1/60th the value. The economy still manages to run just fine, but we spend more on things.
If, for some insane reason, the government decided to do a 10:1 split on the dollar (so for each dollar you have, you now have 10), there would be a bit of disruption in the short term, but things would eventually stabilize with prices exactly 10x what they are today. No new real wealth would have been created, just a massive inflation (or devaluing - more accurate word, but less commonly used) of the currency.
The world ran just fine on the gold standard, and underwent some of the most radical expansions of technology and wealth in society (real wealth, not monetary wealth) with gold. It even underwent sustained deflation, which was good for some people and bad for others (see
http://en.wikipedia.org/wiki/The_Great_Deflation - even as the gold supply increased, the real material wealth increased more, causing deflation).
I don't see any real reason to believe that a gold standard would eliminate innovation and reduce the material wealth of society, because money (be it gold, silver, fiat, etc) is just a representation of that wealth. The economy would look slightly different as there would be more incentive to save and invest over furiously spending everything you have and beyond, but it would function just fine.
The fundamental problem with fiat currency is that you have to trust the politicians to "pull the levers" properly. It can be made to work, but it can also be made to seriously enrich the early recipients of the newly created money (usually politicians and their friends) at the cost of the later recipients and everyone else holding currency. This is all that inflation does - it's a tax on everyone, granted to the recipients of the newly coined money. And it's stealthy, subtle, and a lot less likely to cause riots than soldiers going around to claim taxes.
If I were put in charge, I would attempt to move to a gold standard or similar. It is a much more stable economic system without the distortions of money printing making calculations difficult to impossible going forward, and it eliminates the ability of the government to print vast piles of money for their own purposes. It would certainly be a rough transition, but dramatically shrinking the government is a feature of it, not a flaw, and it should end up as a much more sustainable system that can actually last for a thousand years, instead of the current system we have which will, eventually, end the same as all other debt backed fiat currencies have (in disaster of the hyperinflation variety). Printing more money will not work forever. Never has, and it never will.
