What on earth? You say about scare mongering but it's hard to say anything else when such statements are made. A treaty saying "if you put something out to tender, there should be no barrier over who can submit a tender (but there is no obligation on you to choose anyone)" has absolutely nothing to do with full privatisation.
I mean do you even know what you're saying?
Are you suggesting that if an American company (or frankly any company) has developed a way to improve health that is better than what we currently have/do, that they should be ignored on account of being both a company and American? It's absurd.
The level of debate around this has reached rock bottom. Did you know, for instance, that the Netherlands also have health insurance? Why does no one ever complain about having a Dutch style system forced upon us? I mean goodness, one of those horrible Dutch companies is working already in the Scottish NHS and is starting a trial at a trust in London (

Where was the cry about Dutch style privatisation of the beloved NHS? It's utter bloody nonsense, and scaremongering sums it up quite nicely.
