Historically, every self-described socialist state has been authoritarian to one degree or another. China is the closest modern exception, but much of its economic growth came after it embraced market reforms and allowed significant private enterprise—features associated with capitalism.

Also, healthcare has nothing to do with whether a country is socialist or capitalist. Universal or government-funded healthcare isn’t inherently socialist. It’s simply a public policy that can exist under democracies, monarchies, capitalist economies, mixed economies, and even authoritarian states. Conflating public healthcare with socialism is a basic category error.
