The New York Times ran an article a few weeks ago with the headline "Higher Prices Don't Equal More Care" and the subhead of "American patients use the same amount as those in other wealthy countries but pay more for it." That pretty well sizes up the article.
The article by Austin Frakt and Aaron E. Carroll even had a suggestion or two about possible ways to correct the problem or at least slow down the rate of increase. But the last paragraph came to the inevitable conclusion:
If attempted nationally, or even in a state, either of these (solutions) would be met with resistance from all those who directly benefit from high prices, including physicians, hospitals, pharmaceutical companies - and pretty much every other provider of health care in the United States.
