at the workplace. Michael Newman includes anarchism as one of many socialist traditions. Peter Marshall argues that "[i]n general anarchism is closer to socialism than liberalism. ... Anarchism finds itself largely in the socialist camp, but it also has outriders in liberalism. It cannot be reduced to socialism, and is best seen as a separate and distinctive doctrine." Democratic socialism and social democracy Democratic socialism represents any socialist movement that seeks to establish an economy based on economic democracy by and for the working class. Democratic socialism is difficult to define and groups of scholars have radically different definitions for the term. Some definitions simply refer to all forms of socialism that follow an electoral, reformist or evolutionary path to socialism rather than a revolutionary one. According to Christopher Pierson, "[i]f the contrast which 1989 highlights is not that between socialism in the East and liberal democracy in the West, the latter must be recognised to have been shaped, reformed and compromised by a century of social democratic pressure". Pierson further claims that "social democratic and socialist parties within the constitutional arena in the West have almost always been involved in a politics of compromise with existing capitalist institutions (to whatever far distant prize its eyes might from time to time have been lifted)". For Pierson, "if advocates of the death of socialism accept that social democrats belong within the socialist camp, as I think they must, then the contrast between socialism (in all its variants) and liberal democracy must collapse. For actually existing liberal democracy is, in substantial part, a product of socialist (social democratic) forces". Social democracy is a socialist tradition of political thought. Many social democrats refer to themselves as socialists or democratic socialists and some such as Tony Blair employ these terms interchangeably. Others found "clear differences" between the three terms and prefer to describe their own political beliefs by using the term social democracy. The two main directions were to establish democratic socialism or to build first a welfare state within the capitalist system. The first variant advances democratic socialism through reformist and gradualist methods. In the second variant, social democracy is a policy regime involving a welfare state, collective bargaining schemes, support for publicly financed public services and a mixed economy. It is often used in this manner to refer to Western and Northern Europe during the later half of the 20th century. It
