I always thought that prevention was better than cure. Not according to Nigel Lawson though. Even in the face of all the evidence he would rather that we wait and see. Only then are we to clean up after ourselves. Of course, it could be too late by then.
Lawson was a previous finance minister in the UK Conservative party so we know where his affections lay. Spend no money on the public good unless absolutely necessary.
