After years of reading econblogs, I now understand that the Federal Reserve is not creating enough money.

I can see why inflation can be good for a smallish economy, but [...] (I hardly know anything about macroeconomics, so I'm very likely missing something.)

I think the missing bits here are that (1) creating money needn't necessarily raise inflation, and (2) modest increases in US inflation are unlikely to trigger a mass flight from the US dollar.
