Just read through this thread.
So - the money that we pay for the NHS is going to flow out of the NHS into private companies in order for them to make a profit. This is really scary because making a profit then becomes the most important thing, not making people better. Even if competition for contracts pushes up standards, if profit is the motive savings will have to be found somewhere. So the cheapest drugs, rather than the most appropriate ones; one night in hospital, rather than two; we'll treat you because you can be in and out cheaply, but we won't treat you because you need long-term expensive treatment. Etc.
Just trying to understand ...
In America if you come into A&E after a car accident, for example, they will save your life (basic CPR). But if you need to stay in hospital overnight, or you need any other follow-up treatment like surgery, you have to pay. So if you are unconscious, someone searches through your pockets for your health insurance card, before you get the treatment, before they notify your family. If you don't have the card, you don't get the treatment. Your family come and take you home.
People do die because they don't have health insurance in America. My American friends look at our NHS and drool with envy. Well they used to.
