By 1880, Standard Oil owned or controlled 90 percent of the U.S. oil refining business, making it the first great industrial monopoly in the world. When the Standard Oil Trust was formed in 1882, it produced most of the world's lamp kerosene, owned 4,000 miles of pipelines, and employed 100,000 workers. Rockefeller often paid above-average wages to his employees, but he strongly opposed any attempt by them to join labor unions. Rockefeller himself owned one-third of Standard Oil's stock, worth about $20 million. This is significant because he was a big investor and an important person in the second industrial revolution.
