Vladimir Lenin Quote

Trade unions and strikes cannot help in times of crisis when there is no demand for this commodity, they cannot change the conditions which, convert labour-power into a commodity and which doom the masses of working people to dire need and unemployment. To change these conditions, a revolutionary struggle against the whole existing social and political system is necessary; the industrial crisis will convince very many workers of the justice of this statement.
