In the American business world, the government has a fair amount of control in situations that involve monopolies, as they want to keep the free market open to competition. A monopoly would theoretically remove all choice from the consumer, thus allowing companies to raise prices or otherwise take advantage of their customers. If monopolies are illegal, it theoretically helps consumers because they always know they can turn somewhere else. Recently, Facebook and other tech giants like Amazon, Apple and Google have been in the line of fire. Some believe they are too big and fully dominate their respective spaces, making healthy competition impossible.
