According to Carnegie, what should wealthy individuals do with their fortunes?

Andrew Carnegie famously advocated for the idea that wealthy individuals have a moral obligation to use their fortunes for the betterment of society. In his essay "The Gospel of Wealth," he argued that the rich should promote the welfare of the community and help others through philanthropy rather than simply storing their wealth for their descendants or spending it on personal luxuries. Carnegie believed that the wealthy should invest in public goods, such as libraries, education, and social initiatives, which would ultimately benefit society as a whole. By emphasizing charitable giving over hoarding wealth or extravagance, he sought to encourage a sense of responsibility among the affluent to contribute to the greater good while also enriching their personal legacy through meaningful contributions to society.
