Why did Andrew Carnegie say it is a disgrace for a man to die rich?

Andrew Carnegie believed that wealth should be used for the greater good rather than hoarded for personal legacy. He argued that those who accumulate great fortunes have a moral obligation to distribute their wealth during their lifetime to benefit society. By doing so, they can help address social issues and improve the lives of others, thus leaving a more meaningful legacy. Carnegie saw dying rich as a failure to fulfill this responsibility.
