To solve the problem of identifying which statement can be best inferred from the passage, we must analyze the passage and the provided options.
1. The passage discusses the phenomenon of creating "pointless jobs" in capitalist systems, as opposed to a scenario expected in socialist economies where jobs are intentionally manufactured for employment rights.
2. The passage highlights the contradiction between economic theory and practice, stating that despite market competition, pointless jobs are created, which seems inefficient.
3. The key argument presented is that this practice is not explained by economics but by political and moral considerations. Specifically, it suggests the ruling class finds it beneficial for people to remain employed with little meaningful work to prevent a happy and free populace.
4. An important inference is that there is a deliberate design by the ruling class to maintain control over the working hours of the population through the creation of meaningless work, thus serving their broader plans.
Given these insights, the option that states "Keeping people employed for longer hours serves the plans of the ruling class." aligns best with the inference from the passage, as it directly ties the observed phenomenon to the intentions of the ruling class.
