From Wikipedia:

Democratic socialism has occasionally been described as the form of social democracy prior to the displacement of Keynesianism by neoliberalism and monetarism which caused many social-democratic parties to adopt the Third Way ideology, accepting capitalism as the current status quo and powers that be, REDEFINING socialism in a way that it maintained the CAPITALIST structure intact

Social democracy originated within the socialist movement,[33] supporting economic and social interventions to promote social justice. While retaining socialism as a long-term goal, since the post-war period it has come to embrace a Keynesian mixed economy within a predominantly developed CAPITALIST MARKET ECONOMY and liberal democratic polity that expands state intervention to include income redistribution, regulation, and a welfare state.[41] Economic democracy proposes a sort of market socialism, with more democratic control of companies, currencies, investments and natural resources.[42]
