An attorney with eight strikes of a relatively simple type does not convey to me a strong posture of conforming to the bahavior standards of that community.
If ya' don't like the rules, don't raise your right hand taking allegiance, and then go out and break 'em, often. If you wanna' do your own thing, cool, but I don't have much respect for talking one way and walking another.
If that fits your ad hominem, so be it. If my assessment of the lawyer's background is accurate, I still question his standards of measuring ethics.
On your geographic examples, I've traveled enough to think that none of your groupings are monolithic. Exceptions at all extremes, very flat bell-curves.
Personally, I've got business partners, family friends, three generations, spread over much of northern Mexico. The mutual trust is monumental.
To me "endemic" etc. is not a basis for a group generalization. Opining a trait as endemic is not the same as ascribing a trait to the entire generalized group.
IMHO
