Eve,
You make some good points, and the commentator's points below are also very much on point.

I take issue with you buying into the government's socialist BS whinge that 16% of the population have access to 80% of the Doctors and healthcare providers.

SO WHAT? They are paying for it, on top of paying for the other 20% of Doctors and healthcare providers that service 80% of the population through taxation.
Private medical schemes, like private security is actually another form of tax - people are having to pay twice for services that should be provided for by government by their tax money.

Why stop at healthcare?  Why not transport - I am sure that 16% of the poulation have access to 80% of motors cars and repair specialists - THEY PAY FOR IT!
What next - we all drive around in Trabants?

Please do not stress too much about NHI being impelemented in 14 years time - the ANC will not be in power by then and sanity should prevail.
