A children's prison where you learn useless stuff like addition and subtraction, how an electric circuit works, the human body, and a bunch of other crap I don't understand and therefore don't need. It takes away about 25 hours a day from your life and you're stuck going to school every day for like what, 60 years?
We should abolish the education system. Forget being smart. Let's all be dumbasses and wander around and let society collapse in on itself.
Seriously though, go to school. Aside from learning what you are taught in class, you will also develop social skills and other skills that will help you succeed as an adult.
It's funny how people learn a lot of material in school, and then decide to bite the hand that feeds them by using their knowledge of spelling grammar, and their acquired thinking skills to write a definition on how it's a "legalized concentration camp" that teaches information that "you'll never need." If you're one of the people who wrote such definitions, go ahead and drop out of school. Go ahead and let your mind rot. We'll see who has the last laugh.
