Capitalist Taiwan (the Republic of China) has had such a single-payer scheme since 1995. Malaysia may well be inspired by that system.
Oddly enough, the Communist Peoples Republic of China on the mainland has a basically capitalist health system with millions of uninsured, among them all children. Employed persons in urban settings are covered by a form of social insurance system, but not their children. There’s virtually no insurance coverage in rural areas. Finally, there’s not much of a safety net. Hospitals are not set up to give charity care. There’s no one to shift costs to.
Happy holidays,
