Investopedia explains 'Robber Barons'
Due to the robber barons' unethical business practices, such as the exploitation of labor, the general public typically regards these aggressive capitalists with disdain. However, some historians argue that the late-19th century entrepreneurs usually referred to as "robber barons" - including Andrew Carnegie and John D. Rockefeller - are responsible for building a large portion of the U.S.'s current economic clout, because of their large investments in burgeoning American industries. Many also went on to become high-profile philanthropists.
