Education has and always has had multiple roles for the individual and for society. First, education has significant implications for the economic prosperity of each individual, of each community, of each nation. Technologies and their rapid evolution have changed the business environment, production processes and brought competition from the local to the global level. A well-educated workforce is crucial in the contemporary world, and the fight for natural resources occupies a second place today, ahead of the fight for human resources. Thus education has gradually become one of the world's largest businesses and the private sector has gradually taken over much of the responsibility of lifelong education. Education then has an essential cultural role and implications. It remains the main way in which values and traditions are passed down from generation to generation, shaped to reflect cultural and economic developments, and anchored in reality.
