How to get out of the deficit. If we are going along the lines of a graduate tax how about a Politicians Failed Policies tax. it could have a retrograde as well as a future application. Any politician and advisors would be taxed for the rest of their working lives if they are responsible for a costly and failed policy. The politician/advisor would obviously sign up when the policy is implemented to avoid buck passing.
the retrogrograde part would have to be thought through a bit, but think of what we might recoup from Blair.
