Heh, I wrote much the same thing two weeks ago:

All of these, and many other interpretations, have merit. But there’s another explanation with some salience for Americans bemusedly — or enviously — watching Britain turn into a penal colony with whacky TV and a line of heredity wardens called monarchs.
Britain still subscribes to a system where health care is for the most part socialized. When the bureaucrat-priesthood of the National Health Service decides that a certain behavior is unacceptable, the consequences potentially involve more than scolding. For example, in 2005, Britain’s health service started refusing certain surgeries for fat people. An official behind the decision conceded that one of the considerations was cost. Fat people would benefit from the surgery less, and so they deserved it less. As Tony Harrison, a British health-care expert, explained to the Toronto Sun at the time, “Rationing is a reality when funding is limited.”
But it’s impossible to distinguish such cost-cutting judgments from moral ones. The reasoning is obvious: Fat people, smokers and — soon — drinkers deserve less health care because they bring their problems on themselves. In short, they deserve it. This is a perfectly logical perspective, and if I were in charge of everybody’s health care, I would probably resort to similar logic.
But I’m not in charge of everybody’s health care. Nor should anyone else be. In a free-market system, bad behavior will still have high costs personally and financially, but those costs are more likely to borne by you and you alone. The more you socialize the costs of personal liberty, the more license you give others to regulate it.
