Explain Inflation in Plain Language

Prices keep climbing and the news explains inflation with charts that explain nothing. This covers what it is, how CPI actually measures it, three common causes with one real example each, and what you can do about it personally. No politics, no jargon. For anyone watching their shopping bill creep up.
