A thought or two on Universal Health Care

I keep wracking my brain trying to figure out why anyone would be against universal single payer health care and I honestly cannot figure out one rational reason why.

Here are some of the things that I have heard ...

1. People would go to the Doctor too much. This one is just stupid on its face since I know of not one person that voluntarily goes to the doctor just for fun. Now clearly there are psychologically unbalanced folks that would use going to the doctor as a means of getting out of the house and getting attention but does anyone seriously think that this is a real problem?
   
2. It is too expensive. Again, stupid on its face since if you look at Medicare the overhead rate is far less than it is in any private plan. There is no reason to think that this would be different. This is besides the simple fact that there would be no profit built into the system
3. There would be rationing of services. There already is.
4. It would be "socialism". Big Fucking Deal! Grow up and realize that we don't live in the wild west. We all rely on each other in this society.
