How much are Americans freaked out by the prospect of paying $4 a gallon at the pump? A whole lot ... and not at all. Like a lot of carless New Yorkers, I am generally confused by bursts of populist outrage over high gas prices. But I have always assumed that the anger is genuine — that hard-working Americans, who already spend a lot on gas, are thrown into turmoil when they have to spend even more. After all, 63 percent of Americans insist that these price increases have caused them some financial hardship.
