Which economic perspective would Sumner most likely support?

Sumner is most likely associated with laissez-faire economics, which advocates for minimal government intervention in the economy and promotes the belief that free markets lead to the most efficient and beneficial outcomes for society. This perspective was central to Sumner's views in the late 19th century, as he argued that individuals should have the freedom to pursue their economic interests without restrictive government policies.

Laissez-faire principles emphasize self-regulation within markets, suggesting that competition and personal initiative will naturally regulate supply and demand. This approach reflects a belief in the importance of individualism and the idea that society benefits from the cumulative actions of free individuals acting in their own interests.

In contrast, Keynesian economics, socialism, and interventionism advocate for varying degrees of government involvement to address economic issues and provide welfare benefits, which would not align with Sumner's strong preference for limited government intervention.
