Ms. Lieberman's assertions about the funding of France's healthcare system are inaccurate to the best of my knowledge. The system is heavily financed by employers and employees, based on employment revenues, not on all revenues regardless of employment.
The French system has gone further and further into debt as both the nature of medical care, patients' expectations from it, and doctors' training evolve.
The recourse to extremely expensive technologically assisted medicine, at the expense of sound clinical training, is a disaster for everyone's pocketbook. Moreover, the general public's assumption that this type of medical care is the ultimate in progress and efficiency only aggravates the problem. Add to that the fact that the insurance industry and the insurance mentality ensure that doctors must prescribe sophisticated and expensive laboratory tests for what are often banal conditions that could be treated otherwise, and you have conditions that will bankrupt any healthcare system, single-payer or not.
