One of the main arguments currently being used by those in favour of the Health and Social Care Bill getting through its last stages in Parliament is that most of the changes it would bring about have already started to happen. Those arguing for the Bill say that to stop it now would cause greater disruption than if the changes go ahead.

This is a good, practical argument. It makes sense to people who intuitively know that in their own lives when they are halfway through something – even if they know it was a mistake to have started it – that sometimes it's better to finish it – and then have a think about what to do next.
