High inflation (double-digit, and not necessarily low double-digit annual inflation percentage), such as seen in 1990s Russia, however, is possible. All it takes is a significant economic contraction combined with China deciding they don't want to support the US economy any more.
Where are you in the US that you don't think we have double-digit inflation *right now*? Have you audited all your basic expenses from year to year? I have, and the rate is hovering above 10% for the past 2 years. Why do people believe the official numbers when all they have to do is run a few calculations on Quicken to see that those numbers are ridiculously low?
It's a good point. Everyone has a different level of inflation depending on their spending habits, lgeography, etc. Even basic expenses vary wildly between families, depending on whether or not they have children. Has the price of meat been going up significantly? Yep, but it doesn't matter to a vegetarian.
Anyhow, just to play the devil's advocate, the monthly printing of money won't necessarily cause hyperinflation. Most of that money just gets passed around in derivatives and equities. It inflates those assets, but the average person isn't going to be affected by that. The concern is if the money breaks out of that big circle-jerk of hedge funds and starts puchasing real assets like farmland, cattle, rights to mine oil, etc. There are individuals with enough network who could corner entire markets and cause a massive run up in prices just for fun. When the Chinese start buying up prime farmland in the US, we should get worried.
