Some scholars have said that modern business corporations practice mind control to create a work force that shares common values and culture. They have linked "corporate brainwashing" with globalization, saying that corporations are attempting to create a worldwide monocultural network of producers, consumers, and managers. Modern educational systems have also been criticized, by both the left and the right, for contributing to corporate brainwashing. In his 1992 book, "Democracy in an Age of Corporate Colonization", Stanley A. Deetz says that modern "self awareness" and "self improvement" programs provide corporations with even more effective tools to control the minds of employees than traditional brainwashing was said to have been.
