The professions of teaching and social work are respectable, but not because they can do a better job than parents. Like a dishwasher, they are useful as ways to automate parenting. An automatic dishwasher usually does an inferior job, but it works when a human dishwasher isn’t available. In the same way, no classroom, however well-equipped, can approach the student/teacher ratio, professional dedication or understanding of the students that a committed homeschooling parent can. Public schools stay in business because, like orphanages, they can do their work even without parents if necessary.
At root, many modern conveniences were not developed for people’s needs, but for the Industrial Age. Your automatic dishwasher was not designed for cleaner dishes, it was designed for automatic dishes. You have become used to washing the food off them before putting them in the dishwasher, precisely because it can’t clean dishes as well as you can.
