What is formal education (schools, colleges etc.) actually for? I mean really, properly-speaking?
It seems to have very little to do with literacy and numeracy rates - but even if it did, that can be accomplished by a few years of formal education.
It seems to have very little to do with the transmission of cultural-important knowledge - but even if it does, that can be accomplished by a few years of formal education plus personal study.
It seems to have very little or nothing to do with the inculcation of skills - since these require multiple repetition (drill) and reiteration (practice) which is rare-in, or altogether absent-from, modern formal education.
It seems to have little or nothing to do with developing 'critical abilities' or 'the ability to think' or 'reasoning' or logic or higher levels of cultural sophistication - since all these have either always been absent-from or else are-being/ have-been incrementally deleted from formal education. And when IQ is properly tested, it can be seen that almost all measurable differences in these domains are due to hereditary intelligence, and not to schooling.
It seems to have little or nothing to do with inculcation of good working habits such as hard work and conscientiousness - since most formal education (the great bulk of it) requires neither hard work nor conscientiousness - and such of these as are required are incrementally being eliminated. And when personality is evaluated, it can be seen that almost all measurable differences in hard work. conscientiousness etc. are due to hereditary personality and not to schooling.
It seems to have nothing to do with morality - since success in formal education is already and increasingly possible by cheating (i.e. by presenting another person's work as your own) - so in terms of incentives, modern formal education is a training in dishonesty.
So my conclusion is that, as a whole and on the whole, formal education as it actually is here and now has zero legitimate educational function - beyond the first few years.
It is NOT about culture, knowledge, skills, reasoning, good habits or good morals... and insofar is it operates (imprecisely and corruptly) to evaluate and rank individual abilities, it does so less exactly, more unreliably, and vastly less-efficiently than proper psychometric testing.
So...as a whole and on the whole (with a low percentage of exceptions at the individual or institutional level) formal education has zero legitimate functionality.
That's not very good, is it?
