Step-by-step explanation:
According to John Stuart Mill, the goal of moral and political action should be to maximize people's happiness. Mill's Utilitarianism posits that actions or policies should aim for the greatest happiness for the greatest number, a principle known as the Greatest Happiness Principle. Mill's approach extends this ethical framework to the social and political realms, arguing that governments and politicians should choose policies that maximize general well-being, which inherently involves increasing happiness and reducing unhappiness.
