Socrates didn't charge for "education" because when you are in business, the "customer starts to become right". Whereas in education, the customer is generally "not right". Marketeers are catering to what people want, educators are trying to deal with what they think people need (and this is often not at all what they want). Part of Montessori's genius was to realize early that children want to get fluent in their surrounding environs and culture, and this can be really powerful if one embeds what they need in the environs and culture.
