The Folksy and Simplistic, from Pete Earle
I view the adoration of the folksy and simplistic in finance as yin to the yang of irrational fear and hatred of allegedly "sophisticated"/"rocket science" instruments such as credit default swaps (which are, fundamentally, quite simple) and fundamentally mundane — while ostensibly terrifying — strategies and technology such as algorithmic trading.
It's a form of comforting primitivism, in my opinion.
