The free market run up in cost is one of the reasons why the PPACA got traction to begin with - first under a version endorsed by the Heritage Foundation and many Republicans, and afterwards as the version now in place.
The free market didn't run up the costs. Government intervention did. As it did in education, as it did in the housing market, as it regularly does with the stock market, as it does anywhere it heavily regulates, manages and subsidizes.
