The problem with government-run health care systems is that they generally don't work. I speak from experience. The UK brought in National Health Service (NHS) in 1947, and initially you paid nothing. Nothing for doctor office visits, doctor home visits, hospitalization, prescriptions, eyeglasses, dental care, false teeth, artificial limbs, even motorized "invalid carriages" - little minicars with just one seat.
The result was, or should have been, predictable. People went to the doctor, or if they were lazier, had the doctor come to them, for the kind of trivial things like a cold, that they would have treated themselves before. Everone got their teeth fixed and, in many cases, a full set of dentures. Better eyeglasses and more realistic hairpieces. Lots of people went to the doctor's office just to meet others in the waiting room for a chat.
Within four years the system was costing so much that it couldn't continue in this fashion. Slowly and steadily, over the next 20 years or so, charges (co-pays) were introduced. At first they were trivial - say $2 for a prescription - but in time they became bigger and bigger. The other problem was that the general practitioner became nothing but a civil servant, and could not perform any actual medicine: He acted just as a filtering station, spending maybe 5 minutes, tops, with each patient and making a decision whether to send them to a specialist.
After a few years the strain on family doctors became intolerable. A typical day would be: Open office ("surgery") at 8.30am. See perhaps 40 patients, many having trivial complaints or just coming in for a note to stay away from school or work, or to be OK'd to go back. 10.30, grab a cup of tea and then off on his in-home visits. Back at 12.30 for lunch. Out again at 1.30 for more home visits. Back at 4, grab a quick sandwich. 5.30, Open evening surgery. 7.30, close surgery. Then be prepared for two or three phone calls from people who may or may not have been really ill, sometimes requiring him to set out to see them at, for example, 11 pm or 3am. And if he remonstrated with them for wasting his time he risked being brought up on charges before the General Medical Council.
The divorce, suicide and premature death rate of doctors were the top of all professions. The smart ones emigrated to the US.
Meanwhile, waiting lists for non-emergency surgery became longer and longer. Currently it's around 200 days. How would you like to wait 7 months to have a hernia repaired, for example? Dentists were paid so little by the NHS that a large proportion refused to see NHS patients. The reputed terrible state of British teeth is more than a myth. My sister couldn't get root & canal work or crowns on the NHS; she had to pay herself. Right now, there is a video available showing people how to extract their own bad teeth.
The situation in hospitals is so bad, with the government cutting back on expenditure, especially for staff, that contracting a nosocomial (hospital-acquired) infection, like MRSA, is infinitely more likely than in the US. Meanwhile, the cost to each wage-earner soars through steadily increaing taxes.
Anyone who wants first-class medical and dental treatment in the UK buys private insurance, and this is a big attraction offered by employers to get top employees (BUPA is the best-known company).
Hello? Read that paragraph again. To get proper and timely treatment, people turn away from the government program and use commercial medical and dental insurance. Canadians by the thousands come across the border and pay for treatment here, rather than use their own much-touted government-run system.
In theory, government medical insurance systems are a wonderful idea. In practice they suffer from the same problems that plague almost everything the government gets its hands on - inefficiency, waste, a massive bureaucracy and huge taxes to support them.
Incidentally, don't be fooled by the frequently-repeated left-wing mantra that "40 million Americans are without health insurance." Half of those are illegal aliens, and many of the remainder are young, healthy people who feel that they don't need insurance. (I can relate to that. I was so healthy until my mid-40s that I didn't even have a family doctor because I hadn't needed one).
Out of the much smaller remaining number of actually sick uninsured US citizens, below a certain income level they are covered by Medicaid and/or Medicare. Many states now cover the children of low-income parents, and more are being added each year. And nobody may by law be turned away from a community hospital or denied care because of an inability to pay.
