Obviously the government doesn’t care, they quite like a collapsing NHS so they can sell it off to foreigners and get some kickbacks.
Are you really that ignorant? For all but 2 of the last 50 years the NHS has seen investment above the rate of inflation, by all governments.
The problem is worldwide, progress in medicine now means that even serious problems can be treated, but at huge cost. Understandably people expect their health service to offer such treatments, but how can any such system finance treatments that can cost 6-digit sums every year just for one person?
A bigger problem is getting the money to the right places, not wasting it on unnecessary managers and paperwork to meet meaningless targets, and that's not an easy problem to fix.
