According to Wikipedia. Blue is 'single-payer universal health care', green is 'public universal health care through other means' and grey is 'no health care or data'. You'll note that it's massively underpopulated territories (Greenland and the poles) and the US that are ostensibly prosperous countries without universal healthcare; other wise it's most of Africa (although, let's not forget that not all of Africa is destitute), Arab states, bits of the Indian subcontinent, East-Asian Island states and sparsely populated areas like Mongolia. The US
defines 'developed capitalist state' and yet are over a hundred years behind Germany on health care.
The only criticism I've read out of the US criticising healthcare reform has come back to a general disdain towards socialism. Has anyone read anything reasonable that doesn't go into that? Because I'd hardly say good old Fritz was socialist.
