1. Production of homogeneous labor
In most education systems around the world, students learn the same thing. They grow up to compete for the same jobs. This artificially reduces their future wages. Teach everyone acting all through high-school. I promise actors will make shit money.
2. Education fosters competition when cooperation is the key.
If kids learn different things, they don't and can't compete. A group of adolescents who have all learned a variety of things, from accounting to video production to art, don't need to beg for work because they can band together to start a firm.
3. Hard work does not work in schools-- Agent-Principal problem
We all know the teacher’s pet gets all opportunities. You can work as hard as you want. There is no real incentive for a teacher to give you a fair chance. His income does not depend on who gets the opportunities. He has no skin in the game. By the time kids finish education, they no longer believe in hard work because it never worked before.
4. Unqualified teachers
When I substituted at Starkville High School, Ms. Townsend talked bout HCi. A student corrected her, “I think it is HC1.” “Yes, HC1”, she said. I was probably the only person in the room who knew it was HCL. Nobody found out Ms. Townsend was wrong. Everyone was clueless about how incompetent she was.
5. A distorted vision of the world
Schools put kids of the same age together. This severely inhibits learning. If kids interacted with people of all ages, from younger children to senior citizens, they would have a much more mature picture of life. Imagine if college students knew about Thomas Sowell, who admits to having grown out of marxism, they wouldn’t have to reinvent the wheel. If they hung out with older people, they would learn from their errors.
6. Bullying and mental health issues
What happens when you put a bunch of insecure teenagers together, under the supervision of teachers who are probably less intelligent than they are? It is a mess. The insecurities and the lack of self-esteem cause so many to harm others and themselves. Some are marred for life. Most cases of mental illness start somewhere in middle school or high school.
7. A place for brainwashing and propaganda.
Young adults are vulnerable to brainwashing, especially when there is no one to expose hypocrisy. Seeds of extreme environmentalism, post-modern feminism, and marxism are sown in schools. In religious schools, religion can be used to brainwash the young.
8. A preparation for wage slavery
Most children do not like to go to school. They are naturally reluctant to give up their freedom. However, they are made to give up so much freedom that they become fine with doing everything they are told. They make the best employee. There is a reason why Indians are considered good employees. The education system is so rigid it sucks out their freedom. They are very less likely to speak against injustice. They quietly slave for their bosses.
9 Eliminating critical thinkers
Teachers say they want you to ask questions until you do. During my experience going to school and substituting at public schools, it was obvious that most critical thinkers were in detention. The rest were not liked by their teachers.
10. No useful learning
Differential calculus does not make or break your life. However, you must know how your government works, how to file your taxes, how to buy a house, how to invest, how to get a passport, what your rights are if you get arrested, how to sue someone/a firm, how to use public offices, etc. We learn absolutely nothing we must know. Almost everything we learn besides reading and counting is not essential for dignified survival, rather optional.
11. Loss of productivity
If students do the same projects for the market, they will benefit society and possibly earn in the process. If not, they at least will gain real-world experience. All work they produce in schools and colleges doesn’t benefit anyone, nor do they get paid to do it. In fact, they lose money in tuition.
