Agreed about the racketeers ripping off the health service. Remember the Canadian Pharmaceutical that escalated the £4 drug to £250+ quid over the course of 10 years?

Let's all be careful not to label the NHS per se as flagrant wasting money. The medical employees at the coal-face plus many of the auxiliaries are far from ripping off the tax payer.
There is plenty to change in the procurement process, the PFI nonsense, the racketeers and quangoes that are only in it for the money, and the charlatans such as Mr Branson that sues the NHS for millions when he doesn't get the answer he wants. If that's what you mean be spending more wisely then we are on the same page.
For the record, I'd pay more for the NHS but I would still the above to happen.
