Former President George W. Bush increased 300 tariffs in the final days of his administration; Congress successfully inserted "buy-America" provisions into the American Recovery and Reinvestment Act; French President Nicolas Sarkozy threatened to repatriate auto manufacturing from Eastern Europe; and UK Prime Minister Gordon Brown promised "British jobs for British workers." Desperate times often bring damaging measures. But protectionist acts will only further stifle world trade, thus lengthening and deepening the recession.
