Both but more so the funding model. In the UK we’re in this weird public/private arrangement that for the most part helps private interests extract public capital, whilst making life harder for those working in the service and worsening conditions for patients.
I’m open minded but I think the current public/private model sucks.
Saying new money fixes it is easy to say but until I see a model working I remain unconvinced. Yes people living healthier lifestyles makes a huge difference but even healthy people can get sick or damage themselves sometimes.
