Because of the increased need for a trained labor force to work in growing industries and because the public schools had failed to provide such workers, many corporations conducted their own training programs during the period 1900-1930. Departing from the older methods of training foremen and having them train the workers, these schools provided both general education and job training. Corporate schools especially stressed educating the workers to the "proper" values that would promote corporate efficiency (thus corporate profits), and, according to the prevailing social theory, the good of society would be enhanced. In addition to training workers in specific jobs and molding industrial values, the corporate schools also sought to prepare white, native-born men for promotion to the executive ranks. The corporate schools were so good at their tasks that public schools began to copy some of their methods. By 1930, however, corporate financial troubles caused by the Great Depression as well as union troubles and growing public intolerance of the class-hardening promoted by the corporate schools had caused their demise. Their tasks were taken over by public schools and vocational education programs. (KC)
