Final answer:
Andrew Carnegie's ideas on the social responsibilities of the wealthy were outlined in his book titled 'The Gospel of Wealth.'
Step-by-step explanation:
Andrew Carnegie's ideas on wealth and philanthropy were collected in a book titled The Gospel of Wealth. Carnegie was born into poverty in Scotland but later immigrated to the United States, where he eventually became the leading steel producer in the world through hard work and innovation.
After amassing his fortune, Carnegie advocated for the wealthy to utilize their riches to benefit society by funding public institutions like hospitals, libraries, and colleges, and he practiced what he preached by donating the majority of his wealth to such causes. The Gospel of Wealth expounded on his belief that the elite had an obligation to enrich society and counteract social Darwinism.
