That's because parents have been hornswoggled for the last 40 years or so ... they actually believe that it takes an "expert" to teach a 6-year-old to read and add, or to explain to a teenager why it's stupid and immoral to have sex outside marriage.
I appreciate your position, but I think it's mistaken, and ultimately unproductive, to encourage parents to look to "educators" for guidance in matters that are the province of parents.
I am very interested in your position. We are an expert culture and presume advanced training turns out a better product. If you have information about comparisons between lay persons and professional educators on teaching reading, math and other things, I would be intrigued. I think my phrase: 'look to educators' is meant to imply collaboration not deference or dependency. Part of this expert culture we live in leaves parents as the only non-experts...yet they are the ones who are the most motivated and bonded and interested in how their children develop.
