You guys arguing for state intervention to control supermarkets would have been the same people opposing selling off BT. Can you imagine if BT still had a monopoly on your cell phone? You think you would be getting an iPhone package for £30 a month? The answer is no.
Interesting, BT is something I wouldn't re-nationalise, but they still hold a monopoly over the infrastructure.
But what about the water companies? I can't phone up offwat and ask them whether I can change water suppliers as mine is a little expensive. A privatised monopoly.
