Why are there no models of democratic socialism?

Although no country has fully instituted democratic socialism, the socialist parties and labor movements of other countries have won many victories for their people. We can learn from the comprehensive welfare state maintained by the Swedes, from Canada’s national health care system, France’s nationwide childcare program, and Nicaragua’s literacy programs. Lastly, we can learn from efforts initiated right here in the US, such as the community health centers created by the government in the 1960s. They provided high quality family care, with community involvement in decision-making.
