You obviously don't know what that word means.
You want single payer? Go practice for DoD or the VA. You'll see the future of American health care as you "VISIONARIES" will get it.
Single payer isn't a magic bullet or anything even close. It's just a different set of problems with a bigger bureaucracy running it.
The only things "Single Payer" will mean is more overhead, more costs, and less productivity. Just like it has in every other entity the government has put its paws into. DoD? Education? Social Security?
Good luck, visionary.
