Without context, that’s nothing more than a platitude. In some sense it is perhaps tautological and meaningless since the words educate and indoctrinate could be viewed as practically synonymous. Anyway I’m sure there’s a pithy quote about lacking education and being less educated and/or more poor, but the real question is what is the actual, realistic, practical alternative? There is nothing wrong with choosing not to attend college with eyes wide open IMO, but globally increasing education opportunities is considered to be critical for eliminating poverty. So is Chomsky’s quote even relevant to whether to go to school, or is he critiquing or reflecting on the philosophy of our style of education? The man has a PhD after all.
