The real "producer" lives as a dependent wage earner and never escapes that condition; for that reason the attainment of socialism is a necessity for the proletariat, which must take the political reins in order to organize labor on the basis of free association. Democratic socialism advocated collective prosperity and a more equitable distribution of goods; this was the kind of socialism for all citizens without capital and living from their own labor. The rigid discipline of workers' organizations must characterize the marriage of socialism and parliamentarism, which meant that socialist deputies must be simple delegates of the proletariat. Antonio Labriola cited the "precise and certain" expectations of "critical communism" against the reformists and wrote that social democracy can be taken to mean many things, but never revolution or communism; social democracy and historical materialism should never be confused. The goal of social democracy is the socialist transformation of property through democratic and economic reforms.
