One thing I have noticed about Elders' children is that "Daddy Elder", frequently shields them, by steering any confessions of "sins" to an Elder friend of Dad, to get the most gentle reproof possible.
Elder Daddys will also "mentor" his children on the "hidden" JW rules within the secret "Shepherding" book and unwritten customs to fast-track appointments and privileges for his kids.... if they want them.
So yes, Elders kids do get a boost...but that is normal parental behavior... in my opinion.
But is it HELPFUL to be inducted deeper into a cult???? :) I think not.
