Without entering into the small details of drugs market price: here in Spain we've got universal health coverage. We've got it from back in the 20th century, as most of Europe. Imperfect? Of course, nothing human-made is perfect, and it needs constant tweaking, specially after the 2008 crisis (which still is full-on here). There are inefficiences, waiting lists, etc. But if I ever need a cancer or HIV treatment or a trasplant, I know I'll have it FOR FREE (as long as I know, Spain is one of the world leaders in amount of yearly organ transplants, and I guess this universal healthcare is part of the explanation). And still there's private hospitals and healthcare business with (pardon the pun) excellent financial health. Would some healthcare business in USA have a hard time if universal healthcare was implemented? Probably. But ¿Should this fact stop a clearly benefitial for millions of people policy? About €300 of my monthly pay goes to the State healthcare system. I know the meds my mother needs are much lore than that, alone.
E. Fuller Torrey makes the point in Surviving Schizophrenia that a schizophrenic in New York without insurance will come out ahead financially if she purchases a first class ticket to Madrid, stays at a 4-star hotel for a week and buys all her meds for the year while she's there instead of buying her drugs in New York. That's our world.
