Why an MRI costs $1,080 in America and $280 in France

sellers of health-care services in America have considerable power to set prices, and so they set them quite high. Two of the five most profitable industries in the United States — the pharmaceuticals industry and the medical device industry — sell health care. With margins of almost 20 percent, they beat out even the financial sector for sheer profitability.

The players sitting across the table from them — the health insurers — are not so profitable. In 2009, their profit margins were a mere 2.2 percent. That’s a signal that the sellers have the upper hand over the buyers.
