And after you finish with the OP's issues, maybe you can explain how our current health system (the number of doctors, nurses, hospitals, etc) could possibly handle all the new people accessing free healthcare. I assume you realize that every nationalized HC system in the world today has access problems where people have to wait for months to get certain treatments. You know, like our VA system is today.
First of all, there is no such thing as free healthcare. It gets paid for everywhere. In most civilized countries, taxes pay for the system.
And the wait time argument that conservatives like to flaunt is a shibboleth. It's the kind of argument that people who don't have much interaction with the American health care industry make. Of the ones who do, they don't notice that it often takes a month or six weeks to see specialists, and months sometimes to set up surgeries. And since the systems are different in different countries, asserting that all of them have long wait times is little more than a generalization.
And our VA system only serves a very small percentage of the American public, and it does not have the constituency that a national health care system would.
I always wonder at conservatives who buy death panel myths and cite incidental stories from right wing blogs about whether the National Health covered one procedure or another, and then turn right around and take the fact that their insurance companies do exactly the same thing with no public accountability whatsoever.
Americans take skhy high prices, wait times, and arbitrary control of their health care choices by insurance companies for granted.
People from outside the US are appalled at the high cost, wildly variable quality of service, and lack of accountability in American health care.
American conservatives defend all of these things.
