Charlie Chaplin's film Modern Times has a section where the tramp is working on an assembly line and parts are coming down the conveyor. He has at it and manages to get 10 yards ahead of the conveyor, and has a rest. Just as he is relaxing, the conveyor belt catches up and he has to start again.
In my opinion a lot of the Coalition policies (housing benefit changes, nursing/police/teaching pension changes, reduction in the number of nurse/teaching training places) were like Charlie's conveyor belt. They got a couple or three years of savings but now the belt has caught up. It is almost as if they did not expect to form a second government.
Many colleges are using the legacy syllabus this year. So when the majority of those come back again next year, we will be catching up with the conveyor because of the topics previously on the Higher tier added to the Foundation. I especially like it when a youngster 'taught' (i.e. coached in a smattering of topics) Higher tier can tell me some half remembered facts about the sine rule but has to use her fingers to work out seven sixes...
