The national system of health insurance was instituted in 1945, just after the end of the Second World War. It was a compromise between Gaullist and Communist representatives in the French parliament. The Conservative Gaullists were opposed to a state-run healthcare system, while the Communists were supportive of a complete nationalisation of health care along a British Beveridge model.

If you are relocating the United States, it is important to know that the US does not require all expatriates (or US citizens) to have medical coverage. However, the risk of being in the US without medical coverage is massive hospital bills or even no access to medical care. There are newer requirements for certain expats on select visa types that may require you to have health coverage.
An alternative proposal is to subsidize private, non-profit health insurance cooperatives to get them to become large and established enough to possibly provide cost savings[27][28] Democratic politicians such as Howard Dean were critical of abandoning a public option in favor of co-ops, raising questions about the ability of the cooperatives to compete with existing private insurers.[6] Paul Krugman also questioned the ability of cooperatives to compete.[29]

While politically difficult, some politicians and observers have argued for a single-payer system.[30] A bill, the United States National Health Care Act, was first proposed by Representative John Conyers in 2003[31] and has been perennially proposed since, including during the debate on the public option and the Patient Protection and Affordable Care Act.[32] President Obama has come out against a single-payer reform at this time, stating in the joint session of Congress that "it makes more sense to build on what works and fix what doesn't, rather than try to build an entirely new system from scratch."[33] Obama had previously expressed that he is a proponent of a single payer universal health care program during an AFL-CIO conference in 2003.[34]

Initially the health insurance law of 1883 covered blue-collar workers in selected industries, craftspeople and other selected professionals.6 It is estimated that this law brought health insurance coverage up from 5 to 10 per cent of the total population.
The share of Americans without health insurance has been cut in half since 2013. Many of the reforms instituted by the Affordable Care Act of 2010 were designed to extend health care coverage to those without it; however, high cost growth continues unabated.[3] National health expenditures are projected to grow 4.7% per person per year from 2016 to 2025. Public healthcare spending was 29% of federal mandated spending in 1990 and 35% of it in 2000. It is also projected to be roughly half in 2025.[4]
