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.
