That is true.
"To make all this affordable, France reimburses its doctors at a far lower rate than U.S. physicians would accept. However, French doctors don't have to pay back their crushing student loans because medical school is paid for by the state, and malpractice insurance premiums are a tiny fraction of the $55,000 a year and up that many U.S. doctors pay. That $55,000 equals the average yearly net income for French doctors, a third of what their American counterparts earn. Then again, the French government pays two-thirds of the social security tax for most French physiciansa tax that's typically 40% of income."
And...
"Many French doctors, in fact, earn more by increasing their patient load, or by prescribing more diagnostic tests and proceduresa technique, also popular in the U.S., that inflates health-care costs. So far France has been able to hold down the burden on patients through a combination of price controls and increased government spending, but the latter effort has led to higher taxes for both employers and workers. In 1990, 7% of health-care expenditures were financed out of general revenue taxes, and the rest came from mandatory payroll taxes. By 2003, the general revenue figure had grown to 40%, and it's still not enough. The French national insurance system has been running constant deficits since 1985 and has ballooned to $13.5 billion."
