we are letting the Conservative government take it away from us.
But guess what? The government is our government and they are supposed to represent us - not their own self-interest or their dearly-held personal opinions. US. They represent our interests in parliament and they're doing a bloody terrible job of it at the moment. SO TELL THEM. Use the "They Work for You" website to contact your MP and tell them that you don't want people resorting to private medical insurance because they aren't funding the health service properly.
And if they argue that we don't have the money, point out that they seem to have the money to bomb places and buy a new trident deterrent, and if they don't have the money for the NHS perhaps they could cancel trident or maybe charge multinational corporations a fair amount of tax instead of allowing them to use loopholes to pass money around internally until they don't have any profits left to pay tax on.
Ad maybe, if enough of us do this, we will get our representative to truly represent us, and pay properly for the NHS.
