I have a "right" to own property. I am not "entitled" to a condo on the beach.
I have a "right" to marry. I am not "entitled" to marry Miss California. (Darn...)
I have a "right" to see a physician when I think I need to. I am not "entitled" to have someone else pick up the bill.
But that's the first thing about "National Health Care": getting someone else to pay the bill. The second, of course, is control: eat your peas and carrots, or the System won't pay your bill. And forget that frosty one...
