Well, the education system has a ceiling but also a higher "lower
bound"
In which poor people are "guaranteed" to have it (but then brain
ruined)
However, ultimately, it restricts freedom in class. Most geniuses did not become by Edu System. Lessons restrict freedom and put everyone on equal terms!
As an analogy, it might be the same as putting everyone in prison because some people cannot have food. Now you get it I hope.
