Which group would most likely support the sentiments expressed in a social cartoon?

The sentiments expressed in the social cartoon are most likely to be supported by proponents of anti-monopoly legislation. During the late 19th and early 20th centuries, there was significant concern over the consolidation of power among large corporations and monopolies, which many believed stifled competition and harmed consumers. Advocates for anti-monopoly measures aimed to break up these large monopolies and restore competitive practices in the marketplace.

This group was often composed of reformers who viewed monopolies as detrimental to democracy and economic fairness. The emphasis on equitable economic practices in the cartoon would resonate strongly with those advocating for policies intended to curb the excessive power of monopolistic corporations, making them the most likely supporters of such sentiments.

While labor union leaders, chambers of commerce, and socialist activists may also have objections to monopolistic practices, their motives and goals differ significantly. Labor unions typically focused on workers' rights and issues such as wages and working conditions, while chambers of commerce often promote the interests of businesses rather than advocating for anti-monopoly legislation. Socialist activists would seek more extensive systemic changes than just breaking up monopolies, aiming for a fundamentally different economic structure overall.
