"Sure it'll give your old mum a new hip but you probably paid 10x the actual cost of the procedure through taxation of your entire family."
Healthcare costs and outcomes are pretty well known for developed nations...
NHS - a fully 'socialized' system paid solely through taxes is just about average for developed nations. Outcomes are OK to good, waiting times can be pretty long BUT accessible to anyone. Whoever wants to skip the queues can pay for private treatment by paying directly or through insurance.
US - has fully capitalist system paid directly or through insurance, with one party fighting tooth and nail to remove insurance coverage options for poorer people. Average treatment costs are 2.5 times that of the average for developed nations. Outcomes are good... if you can afford them. If you can't, tough luck.
Switzerland - hybrid capitalist system where basic healthcare is covered by obligatory insurance bought on the open market and regulated by federal government. The costs are about 1.5 times that of the average for developed nations. Outcomes are great, waiting times counted in days not weeks or months.
So, while UK system might not be the best, it's certainly not that expensive and it WILL give your mum a new hip whether she's rich or poor.
"Socialised heath care, like all socialism is inherently evil."
Holy crap, you seem a bit confused as to what 'socialism' actually is. Are you by any chance from a country where it's equated with 'communism', which is a VERY different thing?
