For people who were asking about healthcare elsewhere in Europe, my experiences of the Netherlands (where I'm from) and Ireland (where I live). Having never lived in the UK I can't compare to the NHS.
In the Netherlands, having private health insurance is essentially obligatory. The basic package covers all the essentials and costs around €100 a month. Insurers are not allowed to charge more for pre existing conditions etc.
You still are expected to cover up to €350 or so each year yourself. Most people will also pay more to cover for extras that are not in the basic package such as dental work and so on.
Your employer also pays a chunk of money towards your insurance, and you are taxed on your wages for it too. Allowances are in place to make it affordable for those on benefits or low income. About 15% of the GDP goes on healthcare.
Although my experience is now years out of date, having emigrated, care was excellent. This is what I hear from relatives too. People see their GP for most things, who can refer you on. It was usually easy to get an appointment and referrals were quick. When I broke my foot ten years ago I had an x ray, check by a doctor and a cast in less than two hours. There was no one waiting in a&e. This in one of the biggest teaching hospitals in the country. I was, however, upon arrival, asked for my insurance details.
The Dutch system still relies on the younger, working generation to subsidise those who are not net contributors. Now that the baby boomers are retiring, the system is cracking.
I now live in Ireland. Worst of both worlds. I think the system is supposed to be like the NHS in theory, but it's bloated and overcrowded. I pay €55 for a GP visit. I pay for all medication. Actually, I don't, as I can't afford to go to the doctor unless it's very serious. On the upside, the GP can usually fit us in same day when needed. We do also have private health insurance, but that doesn't cover much until you're looking at hospital procedures. This is mostly to deal with serious illness so we won't be stuck in the endless waiting lists of the public system. I didn't use it to have my children either, as we couldn't afford the €2000+ it would still have cost, plus I wanted a midwife and private care is consultant led only.
The only time one of the DC was ill enough to require the doctor, OOH GP advised us over the phone to go straight to hospital. A wise precaution. It cost us a hundred Euro, which of course we gladly paid. All follow up care has been free though.
Hospitals are overcrowded, often filthy. People waiting on trolleys for days. All that stuff. It's really not a great system.
There are many people in Ireland who have medical cards and get free health care. There is, I think, abuse of the system by some that qualify, similar to what you get in the NHS. My BIL freely admits that he wouldn't take his children to see the GP nearly as often if he would have to pay, but he might as well get them checked out since it's free anyway. I don't begrudge him and SIL their medical card, as it's not their fault they're struggling, but it is nevertheless intensely frustrating that we, as tax payers, cannot in fact afford much of what they take for granted healthcare wise.
