Final answer:
Socialists and Communists worked for social and economic justice by implementing various strategies, such as forming unions, enacting legislation, and calling for revolution.
Step-by-step explanation:
Socialists and Communists tried to work for social and economic justice by implementing various strategies. They sought to eliminate capitalism and establish communal control over the means of production. Socialists believed in a gradual transition from capitalism to socialism, working step by step within the capitalist structure to achieve their goals. They formed unions and organized social democratic parties to protect workers' interests and pass legislation to improve working conditions. On the other hand, Communists called for an immediate and total social revolution, aiming to put governmental power in the hands of the workers. They advocated for the violent overthrow of ruling elites. Both Socialists and Communists aimed to address inequalities and create a more equitable and just society.
