A counter: The NHS is one of the cheapest universal healthcare systems among comparable developed countries. It's run on an utter shoestring.
In other words: You can set budgets and force your providers to do the best they can within them. No matter where you set them, people will be unhappy, but it's not like setting quality as the main motivator means you need to give the provider free reign to spend however much it wants.
PPP adjusted total UK healthcare spending is less than half of the US, despite a significant private sector acting as an outlet for a proportion of the situations when people are unhappy with the NHS. Incidentally US public money per capita going towards healthcare exceeds the per capita cost of the NHS (whether nominal or PPP adjusted). The low amounts flowing to private providers in the UK can be seen as a demonstration that most people considers the NHS service good enough - while many would not be able to afford going private, the proportion who could if it mattered is certainly far higher than the current takeup.
