NHS is useless and the service the public gets for the money pumped into it is a scandal.
Dare to kick up a fuss or criticise you are told "nurses/doctors are so overworked" etcthe NHS seems to do well at hiding poor service behind this mantra.
I suggest you to spend a day with some of the front line staff. Unless you happen to possess first hand experience of the contrary, you are not in a good position to state that isnt true

For the money pumped into it, it is doing rather "well", of course that depends on what you are looking at. For most people in this forum, it isnt doing "well", since we're all mostly young and healthy, with little chronic or life threatening conditions. What we dont realise that if you happen to need the NHS quickly, read RTA/trauma etc, it does very well. If you need it for minor "things" then it may not be as "good".
