Bob is correct here. The other tool people keep forgetting about is fiscal policy; government deficit spending is inflationary, and the US is currently running a very large deficit and was floating even more inflationary ideas like directly bribing voters to vote Republican in the midterms.

Really the problem is that everyone wants to make lots of money (economic growth) so they can spend more (increase consumption) but without anyone else raising their prices as a result. Unsquareable circle.
