Most western European countries have implemented roughly all Demands of the Communist Party in Germany, although some of these have been rolled back in the neoliberal era.

Socialism is one of those heavily mis-defined/used words. I tend to stick to the economic definition. As in "A socialist economic system is characterized by social ownership and operation of the means of production that may take the form of autonomous cooperatives or direct public ownership wherein production is carried out directly for use rather than for profit." (quote from Wikipedia socialist economics). one of the downsides of discussions about socialism is inevitably someone starts using long convoluted sentences like the above.
Socialism as political definitions have been merged and smashed together with communism and fascism in Nazism and conservatism etc. etc.
