Socialism has evolved over the centuries from karl marx's original proposed theories. the first change took place with leninism, and now many liberal societies incorporate a mild form of socialism referred to as social democracy. your analysis should include a comparison of these forms of government and explain how and why socialism split into these several varieties.

There is one difference in that "social democracy" is more clearly defined, European doctrine and practices are both original; while "liberal democracy" is quite vague. What adds to the dellima is that "liberalism" in the US in particular is often tagged with "socialism," even though historically liberalism in the US emerged as a form of defense or what Marx would have called "bourgeois socialism"--socialist concessions designed to protect capitalism, a strategy invented by Bismarck, who was neither a socialist nor a liberal.

Social democrats are inspired by social justice and equity. But they are also democrats, so they rely on the voters to determine those goals. The vogue assumption is that most voters are rational and rationality in the associated sense is that they know how to vote in self-interest. Since more people are poor, working-class, or working middle-class, theoretically, if these people unite to vote in common self-interest, wealth should wind up distributed, in the form of taxes and government benefits, to the majority of the population.
