What 3 ways did Carnegie suggest to dispose of wealth?

Andrew Carnegie suggested three primary ways to dispose of wealth: first, by giving it away during one's lifetime to benefit society; second, through establishing trusts or foundations that would support charitable causes after one's death; and third, by leaving a portion of wealth for public purposes, such as education or cultural institutions. He believed that the wealthy had a responsibility to use their fortunes to improve the lives of others and contribute to the common good.
