John D Rockefeller, monopolist scum and hypocrite to boot. Evil selfish greedy men like this are the reason we have the evil of labor unions to deal with today.
JDR’s “monopoly” broke up dozens of price-fixing local cartels and made heating oil and kerosene affordable to the comman man for the first time
yes, he was hated for all the smaller companies he consumed or beat out of comepetition, but his retail prices expanded the universe of consumers of oil products, downward in the social strata, making kerosene and later gasoline products that nearly everyone could afford
he out-competed others first by finding uses for by-products of the oil refinery process that others were throwing away (letting run in the streams or water table near the refinery), earning more revenue per barrel of oil than his competitors, from which he was able to lower his prices to consumers, from which he was able to obtain a larger market share, from which he had to ship tons of product by rail, from which he could negotiate better deals with the railroads for transporting his products, from which consumer prices got some of that discount and his revenue continued to grow
to everyone else in the industry, and the trust busters, he was a bad guy
to the consumer he lifted everyones ability to join in being able to use the new energy sources
