I think it would make a huge amount of sense for people to be told how much it costs them at point of use for the NHS even if you aren't actually paying at point of use. At the moment in the UK you blindly pay tax into a large bucket each month without any true knowledge of what the public services cost.
It seems like a nice idea.... if you aren't in great need of treatment. The reality that most of us happily don't think about is that we won't get the majority of the value from the NHS service we spend our working lives paying for until the few weeks before we die. We'd like to think we'll go peacefully in our sleep, at home. But more than half of us won't.
When were really, really ill, frightened, desperate, dying... do you really think theres dignity and in being told just how much that all costs?
