Netherlands
While Dutch residents are automatically insured by the government for AWBZ, everyone has to take out their own basic healthcare insurance (basisverzekering), except those under 18 who are automatically covered under their parents' premium. If you don't take out insurance, you risk a fine. Insurers have to offer a universal package for everyone over the age of 18 years, regardless of age or state of health – it's illegal to refuse an application or impose special conditions. In contrast to many other European systems, the Dutch government is responsible for the accessibility and quality of the healthcare system in the Netherlands, but not in charge of its management.
Single-payer healthcare
The United States National Health Care Act is a perennial piece of legislation introduced many times in the United States House of Representatives by then Representative John Conyers (D-MI). The act would establish a universal single-payer health care system in the United States, the rough equivalent of Canada's Medicare, the United Kingdom's National Health Service, and Taiwan's Bureau of National Health Insurance, among other examples. The bill was first introduced in 2003 and has been reintroduced in each Congress since. During the 2009 health care debates over the bill that became the Patient Protection and Affordable Care Act, H.R. 676 was expected to be debated and voted upon by the House in September 2009, but was never debated. In the wake of Bernie Sanders' 2016 presidential campaign, in which a push for universal healthcare featured prominently, single-payer proposals gained traction. Conyers reintroduced his bill in the House of Representatives in January 2017. Four months later, the bill was supported by 112 co-sponsors, surpassing for the first time the 25% mark of co-sponsorship. In September of the same year, Sanders himself, together with 16 co-sponsors, introduced a Medicare-for-all bill in the Senate (S. 1804). An analysis of a Mercatus Center study of the 2017 proposal by economist Jeffrey Sachs found that "it rightfully and straightforwardly concludes that M4A would provide more health care coverage at lower cost than the status quo, projecting a net reduction in national health expenditures of roughly $2 trillion over a 10-year period (2022-2031), while also enabling increased health care coverage."
