There are two systems. One where money is pooled to pay for sick people and is very cheap. Another where money is pooled to pay for sick people and is extraordinarily expensive.
The NHS (the cheap one) should not be deserted in favor of the (private insurance) extraordinarily expensive one. The UK will regret this eventually.
Seems that a government should not hide what it is legally allowed to do - unless the government knows that it is sending people to their deaths. Now, the cat is out of the bag. Shame.
