The length of education, or attendance at supposedly educational establishments, is not the same thing as education itself.
Guerrilla movements in the last half-century or so in Latin American countries, seeking to establish totalitarian utopias, were caused by the expansion of tertiary education, not by peasant discontent.
The graduates of that education
found after obtaining their diplomas that the only work available to them, if any at all, was beneath their new status as educated person, a status that formerly would have entitled them to both respect and an important position in society. If they found work, it was work that they could have done without having gone to university. Bitter disappointment and resentment was the natural consequence.
The equivalent in the West
is the bureaucracy that administers increasingly politically correct regulations. In this way people who have gone to the considerable trouble of obtaining a tertiary education that is of value to them neither vocationally nor intellectually may avenge themselves upon an unjust world.
