Trust
A trust is an economic tool devised late in the 1800's. It was pioneered by men such as Andrew Carnegie of the steel industry and John Rockefeller of the oil industry. The purpose of a trust is to eliminate competition in business. One powerful company will have control of the stocks of many smaller companies in the same line of business, creating a monopoly. The monopoly allows price-fixing and benefits all companies involved. Trusts were outlawed in the early 1900's.
