Economic-based Morality

"[...] Which means that a child’s trust is an exogenously depreciating resource. It’s just a matter of time before they are relieved of it. 

"Given the inevitability of that process you have two alternatives. Deplete their credence yourself and choose what lies they get told in the process, or be always truthful and allow their trust to be violated by outside forces."

Yes, when life is reduced to economics and game theory... I don't regularly read this blog, so I don't know the author well enough to know if he's being facetious.

But really, it's not a matter of losing trust (as though trust were quantifiable; talk about reductionistic physicalism!) but teaching children the principles to differentiate between trustworthy and non-trustworthy people. If the child doesn't learn it from the parents, they will learn it unconsciously through the pain they experience whenever their trust in another is broken. Then the main issue becomes coming to grips with 1) the pain of the failure of the parents to teach the child prudence; 2) the pain of broken trust that is otherwise left unspoken, which will then manifest itself in psychological symptoms.
