A friend and I were arguing yesterday about government stuff and he insisted that the US government does not need the IRS. He claims that the US government/US Dept. of Treasury can just print as much money as they want. I said, "if that were the case, why are some countries poorer than others?" This just didn't seem right, so I insisted that he was wrong, but I didn't have my own explanation. Someone please shine some light on this issue.

The government technically could print as much money as they wished. However, this would cause the money in question to become worthless. Countries that have started to print massive amounts of money have had severe problems (see Germany immediately following WW1). So while it might seem like a good idea to get more money just by printing it, it is a TERRIBLE idea to follow.
