I can't even bear to compare my own four decades of head scratching about economics with Feynmann's insights,

but I can offer you a realisation that I have attained through the kind of haphazard real world that experience the sort of life that I remember reading about in Surely You're Joking Mr Feynmann?

Only to understand why the insight was late in arriving, you see I read Surely.. Joking about when I was ten, and growing up in the bosom of a well to do upper middle class family, with my father retired and mother devoted homemaker and a professor my half brother by our father's first marriage and uncle was a DoD director and scientist who also had no children and was devoted to my early years...

And so I grew up in a world in which I was sure that I could attribute to everyone I met, the possession of a underlying and rational logic, even when I was unsure of how they themselves understood what motivated their decisions.

I'm surveying a decade of watching my life and world in the most complete definition possible, being systematically destroyed. Possibly result of accidentally discovering a corruption of immense and blatant scale.

I learned from this experience, of prison and acquittal ("we should never have been in this court.." began the judge after a five year onslaught of abuse, clearly wrecked my mental health, and irreparably my physical health, I see from my now recovering vantage)...

.... there's nothing that motivates people in any reliable way I see purely random behaviour to be the norm...

And economists are won't to portray the world with the idea of rationality of interests.

Erm.... NOPE!

Try another model....

Oops that's the primary assumption... Okay, back to my aimless broken life, unable to communicate with anyone in normal life because I find no motivation for anything, no systems no values... All outsourced to the Nanny State and red masthead newspapers..

Edit: not in any reply to anyone I've not checked out yet for a update, but I was purposely ignoring the STFUARTFA of econometrics and the various things I have done with along my career, particularly auction and micro markets theory and logic, which I just noted to my loyal but only in title one remaining limited partner is among the memories that I have been thoroughly unable to recall of in any part of my work, which spanned more than half of my years on this planet. I certainly know that economics is far beyond the kind that The Economist newspaper is given to making accessible to proverbial common man hypothetical problems and quandary. I never thought that economics was ever limited and possibly that same belief in the limitless application of Economic Theory (intoned with great reference by all who utter the wisdom denounced from whom they are unable to question, not because they lack the ability, but because they are presented with unintelligible morass of signal free human volume)... May be that that limitless applicability which is the candle that will burn both ends forever in some kinds professionally employed as economists, is precisely what should have been the very warning sign, alerting us to a problem. I mean, has any other profession, reached across the desk, and leaning over the work of a unrelated practitioner, suggested that their input was capable of unbounded insights and discovery? Yet, like the populous hope for Panacea or else a Soma, we all have our moments of susceptibility...)
