In 1889, Andrew Carnegie, then the wealthiest person in the world, wrote an essay called "The Gospel of Wealth." In the paper, he laid out the core principles by which he lived.
Carnegie said he believed the wealthy were only temporary custodians of their bounty and they had a moral obligation to use their wealth to accomplish some common good. Mr. Carnegie said wealthy people should set an example of modesty, shunning ostentatious lifestyles and displays of extravagance.
Furthermore, Andrew Carnegie said the person who dies rich, dies disgraced - that people should give away their wealth while they are still living.
I grew up going to a library Mr. Carnegie's money built. His wealth built thousands of libraries all over America. Before he died, the Scottish immigrant had given away 95% of his wealth and blessed millions of people like me.
