Your topic seems a bit more about how to fix the economy rather than currency, though you suggest currency as the solution to the economy.
Increasing the money supply lowers the demand, therefore requiring more money for the same purchase. That is the only way printing more money affects the economy. However, budget cuts don't save an economy in the first place, despite what bullshit Republicans preach. Some legislature also doesn't fix the economy either.
I will say that for one thing, you don't fix an economy. An economy fixes itself. There are natural highs and lows caused by capitalism and the free market system in the economy. The world is currently in a recession, which is typical low that occurs every decade or so, sometimes even less. Recessions result from small bubbles in the economy. However, every once and a while a really big bubble comes along, and when it bursts it causes a depression.
A depression is where the government needs to step in to speed up the process of fixing the economy. If a depression lasts long enough, consumers lose trust in producers which can create a very long slump in the economy. The government can fix this, in theory, by two ways. And they are polar opposites. One is increasing taxes, the other is decreasing taxes.
Each have their own benefits and costs. Decreasing taxes is a right wing approach, leaving more money with the consumer to make financial decisions to stimulate the economy. This, in theory, would work very well to end a financial downturn. However, in uncertain times, consumers are less willing to spend their money in fear of getting hit hard by the bad times. So really, this will more often stagnate the economy. However, it could work if the population don't act timid or scared.
Raising taxes, the left wing approach, gives more money to the government, who in turn should spend it on recovery operations, intended to provide jobs, goods, and services to their citizens. This is to be a very effective way to get out of a depression, as the government should have no qualms in spending money for the sake of their country. Again, this has it's downsde as the government does rack up debt for the country. However, if it spurs the country out of depression, the country should easily be able to pay off the debts incurred when the economy is catching up to speed again.
I personally supports a left wing approach to a recession/depression, though I recognize both sides have their pros and cons.
