I really can’t add much to what
Thomas Sowell so elegantly states:
When amateurs outperform professionals, there is something wrong with that profession.
If ordinary people, with no medical training, could perform surgery in their kitchens with steak knives, and get results that were better than those of surgeons in hospital operating rooms, the whole medical profession would be discredited.
Yet it is common for ordinary parents, with no training in education, to homeschool their children and consistently produce better academic results than those of children educated by teachers with Master's degrees and in schools spending upwards of $10,000 a year per student-- which is to say, more than a million dollars to educate ten kids from K through 12.
Nevertheless, we continue to take seriously the pretensions of educators who fail to educate, but who put on airs of having "professional" expertise beyond the understanding of mere parents.
