AIG is not the only company making questionable use of American taxpayers’ dollars. Away from the glare of congressional hearings, the two crippled Detroit carmakers, General Motors and Chrysler, are cranking up discounts, low-interest financing offers and other promotions in the hope of persuading Americans to buy more of their cars and sport-utility vehicles.

Their goal is not so much to make a profit as to keep assembly plants running and maintain market share, thereby helping to convince lawmakers that they are viable businesses deserving of more government aid. Detroit became hooked on incentives after the success of GM’s Keep America Rolling campaign in the aftermath of 9/11. Interest-free financing for up to five years played a big part then in jump-starting car sales and rebuilding consumer confidence.
