George Watson reminds us that compulsory health insurance began with Bismark's Prussia in 1883:
That created a sudden panic on the left. Karl Marx had died weeks before, so the socialist leader August Bebel consulted his friend Friedrich Engels, who insisted that socialists should vote against it, as they did. The first welfare state on earth was created against socialist opposition.
Watson extrapolates a larger lesson:
The forgotten truth about health provision is that socialism and state welfare are old enemies, and welfare overspending is a characteristic of advanced capitalist economies. Nobody doubts that California is capitalistic, and its public debt is notorious; the People’s Republic of China, by contrast, is a major creditor in international finance. When the two Germanies united after 1990, the social provision of the capitalist West was more than twice that of the socialist East, and the cost of unification to West Germany proved vast.
