Moral Hazard?

In the New Yorker article, "THE MORAL-HAZARD MYTH - The bad idea behind our failed health-care system.", Malcolm Gladwell sheds some light on how The USA manages to be the wealthiest country in the world and yet allow a huge proportion of its population to live with third world standards of healthcare. I found it shocking reading, and a grim warning to us in the UK of what we have to lose. The article doesn't address the financial aspects of the issue, but it seems likely that the cost incurred by society due to the endemic ill health and suffering would outweigh the saving in taxes.
