[Remove]Economic growth increases the supply of money by more than it increases demand so prices don't rise.

Question for Americans - why aren't you all rich? It seems like your economy is growing forever and you all have really good jobs that pay really well. I would expect everyone to be really rich by now so how come they're not? I am Australian.<br><br>Also, I don't get this whole "inflation" thing. It seems like a made up word. I would expect that a growing economy increases the supply of money more than it increases the demand for money so prices would actually *fall*.<br><br>The finance people in my office say that interest rates are used to control inflation but I can't see how that works. If the economy is growing really fast then surely interest rates should be really low to support that growth? Why would you want to slow it down?
