Like a Fourth of July crescendo of fireworks, our gasoline prices are rising higher and higher. While this is tough on consumers, we're assured by a covey of tongue-clucking industry analysts that nothing can be done about it, for it's simply the law of supply and demand in action -- so suck it up, and pay up.

What's going on here is not the "magic of the marketplace," but some hocus-pocus by brand-name dealers. What might surprise you, though, is that the wheeler-dealers now jacking up our pump prices don't operate under the BPExxonMobilShellChevron brands -- but the logos of Goldman Sachs, Morgan Stanley and other Wall Street traders that have been placing vast, unregulated, secretive bets on the future price of oil. They're playing an electronic casino game in a global "dark market" of exotic derivatives and credit swaps.
