I think we may be talking about two different things. I'm referring to price inflation ( a bad thing), which may lead to hyper inflation ( a really bad thing). Monetary inflation has occurred since the Federal reserve was established. A dollar then is worth a penny now. People loose jobs and the economy goes to hell during extended monetary inflation. Remember Jimmy Carter?

There are a LOT of lies about the Great Depression. History is typically a lie so I don't believe much of what I hear about the Great Depression

Why would an economy contract during a period of monetary deflation? If my dollar is worth more today than it was yesterday couldn't I buy more stuff with it? Wouldn't that cause demand to increase? Wouldn't that be an an economic expansion? Wouldn't more people gain jobs?
