Inflation on some key commodities over the past two decades:
Things with fairly inelastic demand that have been around forever – food and cars and the like – held fairly steady.
Technology in unregulated areas, driven by the free market’s desire to help people keep up with the technological joneses? In free fall (and that’s not even counting price per unit of performance).
Prices in areas heavily regulated by and/or dependent on government? Skyrocketing.
