The English-only movement seeks to make English the sole language used in governmental affairs, such as ballots, schools, and so on.
Ludwig von Mises writes that "the problem of compulsory education has an entirely different significance in those extensive areas in which peoples speaking different languages live together side by side and intermingled in polyglot confusion. Here the question of which language is to be made the basis of instruction assumes crucial importance. A decision one way or the other can, over the years, determine the nationality of a whole area. The school can alienate children from the nationality to which their parents belong and can be used as a means of oppressing whole nationalities. Whoever controls the schools has the power to injure other nationalities and to benefit his own."
