Why gasoline in the United States is really so cheap

Despite daily headlines bemoaning record gas prices, the U.S. is actually one of the cheaper places to fill up in the world. Out of 155 countries surveyed, U.S. gas prices were the 45th cheapest, according to a recent study from AIRINC, a research firm that tracks cost of living data. The difference is staggering. As of late March, U.S. gas prices averaged $3.45 a gallon. That compares to over $8 a gallon across much of Europe, $12.03 in Aruba and $18.42 in Sierra Leone.
