Well I dont agree with a hard and fast quota, however to keep the infrastructure in place working and to plan one must have some sort of goal. Otherwise you end up with the situation we have at them moment, A&E in some areas knackered and people in Birmingham having to send their primary school kids out of the City. Crazy, just breeds resentment.
The problem any Government would have is that they would be slated if they undershot the Goal by some and slated if they overshot the goal by others.
