Is inflation a good or bad thing? Why do governments want some inflation?
Inflation is theft!  It is caused when banks lend money that someone deposited, but still has claim to - called fractional reserve banking.   On top of that, the Federal Reserve Bank (in the US) or the Central Bank of the currency (i.e. Bank of Japan, European Central Bank, etc.) can increase the monetary base by writing checks out of thin air to purchase debt, such as US Treasury Bonds. Inflation is not a natural phenomenon, it is completely man-made, and is caused solely by the two methods above. Inflation causes the business cycle.  Lower interest rates caused by inflation cause long-term investment, even while savings is actually low and consumption is high.  This causes prices to rise rapidly (the boom), and eventually, when the realization is made that the savings is not there to consume the products of the investment, you get the bust. I would encourage you to read or listen to The Case Against the Fed by Murray N. Rothbard - Great book, free online or via iTunes.
