'We tortured some folks,' Barack Obama admitted the other day, in a speech hailed as an unflinching mea culpa for the post 9/11 'enhanced interrogation' programme. It's not the first time Obama has reached for the F-word. In a speech in New Britain, Connecticut, earlier this year, Obama addressed the spiny question of the US's yawning inequality. 'There are folks at the top who are doing better than ever... we understand that some folks are going to earn more than others.' Happily, the president was battling to make sure 'hardworking folks' got a rise. They included the good 'folks who are cooking the meals of our troops, or washing their dishes, or cleaning their clothes. The country should pay those folks a wage you can live on.'
