Gary Becker gets to the biggest aspect of our cost growth in my view- insulation from out of pocket spending-"Here in the United States," Mr. Becker says, "we spend about 17% of our GDP on health care, but out-of-pocket expenses make up only about 12% of total health-care spending. In Switzerland, where they spend only 11% of GDP on health care, their out-of-pocket expenses equal about 31% of total spending. The difference between 12% and 31% is huge. Once people begin spending substantial sums from their own pockets, they become willing to shop around. Ordinary market incentives begin to operate. A good bill would have encouraged that."
