What do you consider affordable? I've seen people that made minimum wage, and had health insurance. I have health insurance, and last year I barely broke $20K income. So what exactly do you consider "no insurance that's affordable"?
Over 1,000 cancer patients refused drugs by NHS managers
Let me explain a bit what's happening in the UK right now. The system can't pay for itself. There's more patients, then there is money. So the government has instituted a "postcode lottery" where people with one postcode (read zip code) can get expensive drugs, and people from another postcode can not. This would be like people from the New York zip code being given the best of drugs, while people from Buck Creek, Indiana can not.
Moreover, some new more effective, but more costly, drugs for kidney cancer, are simply not available at all. It's not that they are too expensive to get, or that they are difficult to find, they are governmentally prohibited from selling them.
So you want to complain because your friend need $400 for his meds? Tell me, how much better off would your friend be, if the drugs were not available at all, or if he was just in the wrong postal code to get them?
The problem with the socialist view is, you are very good at complaining about how things are. Not very good at seeing how much worse it could be.
