Prevent NHS GP's charging for expedited appointments

Waiting time for appointments should depend on need not the basic ability to pay. Do we need to go back to pre NHS times just so extremely well paid GP's can increase their coffers? It is basically dangerous. Already the poorer members of our society have a lower life expectancy and generally poorer health, paying for a GP will just excesserbate the current situation. GP appointments for medical reasons, should always be free at the point of contact and remain a basic tenet of the NHS.
