The one I intended to write was how cost effective the NHS is compared to the American model (we pay less in taxes for healthcare than Americans do).
The important one is PSA: Always haggle over hospital bills in America. The numbers are pretty stark. Hospitals expect to only be paid just over a quarter of the amount they charge. And this overcharging of course affects those with the least specialist knowledge of the field - in other words those who aren't paying insurance companies a large amount of money. In other words those who are most vulnerable.
