Schooling

The purpose of the different schooling levels:

Elementary school - gives you the basics of learning, building blocks
High school - builds on the foundations and prepares a person to begin their real education
Bachelor's degree - teaches a person how to learn
Master's degree - teaches a person how to question
Philosopher's degree - teaches a person how to think

And people wonder why our world is so off kilter... we don't have enough people that have been educated to the point of being able to think. Please note that when a person attains that level, most other people at lower levels will listen to what they have to say. There's a reason for that.
