State socialism

State socialism is a term that's sometimes used interchangeably with State capitalism. It's often defined as the state ownership of the means of production. This is contrasted with Libertarian Socialism, which involves collective ownership of the means of production without state intervention. Trotskyites believed that Stalinism was state socialism and not true Marxism. Modernly, many European political parties on the left side of the political spectrum advocate varying forms of state socialism, one type being democratic socialism.
