The big difference from Medicare is that everyone is entitled to receive care under the NHS. Not just emergency treatment at hospitals, the lot.

As for the USA, I can understand why there may be people working for insurance companies, or getting money from investing in them, who would be scared of a change that might threaten their livelihood or their income. And I can just about understand that there would be some doctors and so forth who might be frightened of a change that they have been told might threaten their income and job security.

But why people whose only involvement with the health system is as patients or relatives of patients should be frightened, that is very hard to understand.

The propaganda put out by the insurance companies and such must be incredibly clever adverts to get people to believe that they should be frightened of change.

Belloc's words seem to sum up that attitude prettty well:

"Be sure to keep good hold of nurse
For fear of finding something worse"
