"In the Universal health care system, healthcare services, including free screening examinations for particular diseases, prenatal care, and infectious disease control, are provided by national and local governments. Payment for personal medical services is offered through a universal health care insurance system that provides relative equality of access, with fees set by a government committee. People without insurance through employers can participate in a national health insurance program administered by local governments. Since 1973, all elderly persons have been covered by government-sponsored insurance. Patients are free to select physicians or facilities of their choice."

"Universal Health Care System" is a difficult qualitative factor to defend, so competing institutions will have an easy time overcoming it.
