The Price of Gas

Another great letter from Don Boudreaux:
Mark Segraves reports today that Maryland Attorney General Doug Gansler, having received complaints about rising gasoline prices, "sent a letter to [gasoline wholesaler] Empire requesting documentation to justify the spike in prices." 
Here's how I hope Empire will respond to Mr. Gansler's letter...
One of Don's great gifts is in whittling down an argument to the simplest possible terms so that anyone with an elementary level of education can follow along. The whole thing reminds me of a point I made awhile ago, to whit: if oil and gas companies are so mercenary and all-powerful in their pricing practices, then why are gas prices so low?
