Teachers Are Racist Against Children

As any concentration camp guard must be racist against their inmates. Holds tremendous spite and artificial contempt, the loser's combination. The spite shows they think, deep down, the children rank above them. 

Example: homework.

If you ask a properly "educated" modern why children are never allowed to have initiative, they will tell you they're irresponsible and can't be trusted.

In reality this simply isn't how children work. They want to help and become grownups, and will sit and learn if they need to. The problem: they don't. 

All scholastic interventions wash out within two years, and usually sooner. Homework will help you on a test a month later and is worthless on a test a year from now, a fact even Official Science cannot deny. A fact even the allegedly dumb, irresponsible children immediately understand, which is why they hate homework so much. Under ideal conditions, it is a waste of time. Cyanide is bitter and you don't need to be "educated" to recognize you shouldn't eat it; homework likewise. A fortiori, how well must adults understand that homework is good for nothing except inflicting pain?

Bonus round: a good job is one you can leave at the job. If school was in fact about preparation for life, it would conspicuously oppose doing any work at home. University in particular attempts to consume the "student's" every waking moment, at minimum. The practice is implemented for the opposite of your health.

Double bonus round: can you think of a single real-life situation where you were glad you did your schoolwork? I can't. Even if you can, was it worth 13+ years of opportunity cost for that benefit?

A teacher is someone who knows their victims forget everything over the summer, and hate everything that it is a teacher's job to inflict. They went to school too, after all. The teacher voluntarily takes and keeps that job anyway. Motivated by pure sadism.
