there are ways the NHS could recover some costs.
meals whilst in hospital for instance. i was in southampton general in 2016 for an aortic aneurism stent. the meals were fine. and free! why ? there was an obese east european type in the bed opposite who did nothing but moan about the food--it was free--served hot to the bedside--and i bet it was a lot better than the crap he was used to.
our NHS is the envy of the world--even with its various faults. i have had excellent service all my life.
NHS dental treatment--i have to pay a fixed fee for any treatment--but free for people on means tested benefits.
eyesight tests--free for me as a pensioner
prescription meds---ditto.. can you imagine that--free meds !!
