"The discoveries of healing science must be the inheritance of all. That is clear. Disease must be attacked, whether it occurs in the poorest or the richest man or woman simply on the ground that it is the enemy; and it must be attacked just in the same way as the fire brigade will give its full assistance to the humblest cottage as readily as to the most important mansion. Our policy is to create a national health service in order to ensure that everybody in the country, irrespective of means, age, sex, or occupation, shall have equal opportunities to benefit from the best and most up-to-date medical and allied services available." - Winston Churchill, March 2, 1944 address to the Royal College of Physicians
Via Joe Conason's article "Winston Churchill was a Bolshevik."
I'm a bit skeptical about exactly how sincere Churchill may have been, given his having made the now demonstrably false F.A. Hayek argument that the welfare state ideas of Labour would lead inevitably to serfdom, but I think Conason's general point holds, and that its pretty clear you can support the creation of a public health care system without being a commie.
