Why are U.S. citizens ignoring the 6% gain on GDP, by not nationalizing health care?

Statistics show that the average U.S. citizen pays considerably more for their, --- bankruptcy creating inhumane medical system, --- than other countries who have nationalized health care. The gain in GDP is around 3%.

It follows economies of scale gains are likely to be about 3%. If a penny saved is a penny earned, I am justified in saying that there would be a 6% saving to the average U.S. citizen.

Why are Americans wasting such a huge amount of gains, when going single payer could bring such a huge gain to each American?

I ask all my Yankee friends; what the hell? Recognize that single payer, pays great dividends.
