Education does not prepare students for the real world, because many lessons are not applicable to the real world, proper lessons about mortgages aren’t taught, and students only compete for a letter grade.
Lessons in subjects such as math are unlikely to come in handy in the real world. However we still spend a lot of time learning about subjects like the theorems related to a triangle.
Often times lessons about mortgaging, sex education, and getting and performing well in jobs is barely, or isn’t at all, taught.
Students in school only do work to get a good grade. By the next year a student will have forgotten most of what they had learned due to the stress of getting an A.
