Two years ago, David Cameron's UK government began the slow process of rolling out a series of changes to what remained of British social democracy. Someone had to pick a date when a lot of the major reforms would come on stream. Quick quiz: did the government nominate April 1 because it was 1) so confident in its political rule it thought it could have a bit of a larf; 2) so confident in Labour's political ineptitude it didn't think it mattered; or 3) so disconnected or incompetent that no one actually noticed?
