“The more solid the family foundation, the more likely you are to be able to resist peer pressure. Human beings are social creatures. We all want to belong, we all have that desire, and we will belong, one way or another. If the family doesn’t provide that, the peers will, or a gang will, or you will find something to belong to. That’s why it becomes so critical for families with young children to understand what a critical anchor they are.”

I can not adequately rate this with mere stars on any scale. We hold this truth to be self-evident and absolute. Commencing with the family of Man (our Eternal Progenitor being King) through our corporeal nuclear ménage, the family foundation is the founding building block of each/every-any/all societies. In a college economics class, I remember the professor explaining how the family unit was even the pecuniary basis of society's (local to national) financial exercises. By example: if only one individual worked per household, costs would ultimately relate that scenario (cost of home, food, vehicles, etc.) If two persons worked per household, prices would rise to reflect that norm — etc. Study after study has shown, two parent family units that relate with their children have a greater likelihood of educational advancement, mental and physical well being, etc., etc., etc. 

"If you stand straight, you don't fear a crooked shadow."

That's a really insightful point about family as an anchor. It makes so much sense that a strong family unit can provide the support and belonging kids need to navigate peer pressure.

Observed no behavioral character differences in "peers" or "family" alike.  A personal independence direction is the only choice available.
