Good and harm
Andrew Carnegie was considered a philanthropist. He used a large portion of his wealth to build libraries and otherwise used his wealth to improve education.

On the other hand, he was brutal to his workers. He continually tried to destroy labor unions that his workers formed. In 1892, a militia was used against his workers, in order to destroy the union.
