The railroads and grain elevators were not the only types of "big business" that began to generate wealth while also aggravating ordinary Americans.  The biggest and wealthiest business of all, perhaps in the entire history of mankind, was built by John D. Rockefeller to control the production and supply of oil.

Oil has been used since the Ancient Greeks, who would pour it into the sea and then set fire to it in order to defend against attacking fleets of ships.  Noah may have used thick oil (called "pitch") to waterproof Noah's ark.  Moses' basket may have been made waterproof using oil, just as American Indians used it to waterproof canoes.<ref name="Oil">http://www.seed.slb.com/qa2/FAQView.cfm?ID=906</ref>

But the first modern oil well was in Pennsylvania, when Colonel Edwin L. Drake drilled down 72 feet near Titusville (just east of Pittsburgh) and struck "Oil Creek."  Oil production there started in 1859.  That oil sold for $40 a barrel (note that a dollar was worth far more then), so it was even more expensive to buy than oil is today!  It was used for medicine, as there were no cars then.<ref name="Oil"/>
