Is inflation a good or bad thing? Why do governments want some inflation?
Inflation, like trade deficits or surpluses, have winners and losers in an economy. Clear losers are people who are on a fixed income, as they often have a fixed income and a prices keep on going up, meaning they can afford less.  Numerous articles on the internet discuss the inflation of the 1970s, here are Google's results.  I'm not so sure that governments want "some inflation" as much as they desperately want to avoid deflation. Deflation means that the price for today's product, like a car, will decrease in price tomorrow (or a month from now) which creates a powerful incentive for people to put off a purchase until later, which brings consumer demand down in a country's economy.
