I have seen, first hand, over many, many years the damage done to children (who grow into damaged adults) by public state/government schooling. I confirm, without doubt, that state school is rigged against those it claims to help. The state does not, as you say, "give a rats fuck" about the common fiat slave. Teachers who finally see the system can never be "fixed", is not broken but, in fact, specifically designed to keep citizens uneducated quit disillusioned, leaving behind the largely naive, brainwashed unintelligent ones, who are still in deep slumber (with few exceptions). These ones are not going to help your children become curious, life long learners & critical thinkers as they blindly follow rules & never question the whole bullshit system themselves.

If the aim is to simply have individuals with a basic standard of written and mathematical literacy, that is very easily achieved! And yet, this basic objective is staggeringly being failed to be implemented across the developed world! That is because it is not designed to produce educated citizens. It is designed to produce brainwashed slaves, who follow orders. The "education system" is a con (a confidence trick). It is exists to achieve the opposite.
