Just my tuppence worth...
I think there is clearly two parts of the NHS argument, the infrastructure and the personel. The infrastructure varies massively, under invested vs state of the art depending on where you happen to be and what you are there for. As Chesterfield mentioned, the country slips further and further into debt, there isnt enough money to go around, how do you invest? You cant, you simply mantain where you can.
The people though, really are something, fantastic utterly fantastic and I wouldnt swap the people of the NHS for any other around the world.
I lived in both Japan and France and by some bizarre twist of fate broke my hand in both - right hand in japan left in France.
In Japan I kinda just left it until it went very black and the pain killers were doing nothing so went to a doctor who looked at it, said it was broken, said I was lucky it naturally set in the right position and also thought I was mad for putting up with the pain - that cost me about £150 for a chat and a bandage.
France I waited for 5 hours in the hospital (and this is in central paris not out in the stix), before being seen at 2am in a room where I sat on the edge of a bed and looked down to see dried blood spots on the floor, then having to pay an Ambulance 65 euro to take me to another hospital (they took me in the back and stopped at a cash point to get the money as my fingers pointing in all the wrong directions tried to press the pin numbers in - imagine the scene from Blade Runner where Ford has his fingers broken and the gun put back in his hand!) then finally, 8 hours after walking into one hospital, walking out of another with splints on my fingers.
Trust me guys, the grass isn't always greener...
