I guess they are the result of a type of helicopter parenting lots of universities have been complaining about.
The problem is not limited to just JW Kids though, but it is more a general western society thing. So much so that even Jordan Peterson assigns one of his 12 rules for life to this, namely, his 5th rule "Do not let your children do anything that makes you dislike them".
But as spiral mentioned, JW kids have a huge disadvantage on top of this for "striving to not be part of the world".
