The ones who don't conform like good little subjects get punished accordingly.
That's actually one of the intents of the public school system. It isn't socialism, though. Conforming to the demands of authority and socialism are 2 different things.
The schools system's
structure was designed to create obedient workers to feed the industrial revolution. Ding. Move on to the next task. Ding. Move on to the next task. Ding. It doesn't get any more capitalist than that, except the student isn't the capitalist. He or she is the potential wage slave of the capitalist.
Make no mistake: this is not socialism. It ~is~ indoctrination but not into an ideology. Into an economic class that is accustomed to depending on his or her "superiors" for work, wages and instruction.
This is not the fault of the teachers or the administrators. It was set in place ages ago in the paradigm of what we think school should be. Lobbied for, along with mandatory schooling, by the fathers of the industrial revolution and the central banks that funded it.
Welcome to America, kid. Now sit down, shut up and let me teach you about how free you are.
