Mary Edna Tobias Marcy, Shop Talks on Economics — High Prices and Monopoly Prices (1911)
“ No man was ever able to raise the general price of a commodity at will, and get that price. If any man ever held such power, he would have charged an unlimited price for his commodity and immediately assumed the world's dictatorship. John D. Rockefeller may be able to raise the price on oil in certain communities, but he cannot force men to buy at this price. So-called monopolists are subject to economic laws just as are wage-workers. No monopolist was ever so great a philanthropist that he did not charge all the traffic would bear at all times. ”
