In the PDF downloadable from Dr Clark's website, he mentions a paper suggesting that behavioural traits in wild dogs can be modified in as little as 8 generations, but without seeing the paper he's referring to

Google 20 generations foxes.  First link is this:

Lots of evidence for human inheritance of psychological traits.

to tell if this is extrapolable to humans over 20 generations or if Dr
Clark is grasping at straws.

Do you have a cite for that?  Money had been around a *long* time,
well over a thousand years before the period Clark was investigating.

One school of thought is that Protestantism encouraged a diversity of thought and founded new educational institutions that encouraged inquiry into the new and weren't obsessed with traditional learning (and it's true that many of the early industrialists studied at Protestant academies because as non-conformists they couldn't study at Oxford or Cambridge, and the industrial revolution kicked off in Birmingham, a town with many non-conformist churches).

The anglo-saxon legal code based on contracts and a society based on loyalty, where oath-breaking would get you branded publically, formed a solid foundation for laws respecting personal property and allowing a strong basis for commerce. The early industrialists of England included a lot of Quakers, and the early Quakers were noted for bringing their accounts to church so their fellow worshippers could check the honesty of the accounts. By establishing a solid reputation for business ethics, this religious sect came to have a huge influence on British commercial life. Compare this to our current troubles in an age where huge financial instruments are only worth what people believe they are worth and people spent several years talking them into a bubble, "mis-stating" the accounts is rife (and the SEC has to frequently punish big corporations), and you see the difference between the current business culture and that of the industrial revolution.

None of these idea preclude genetic selection from having a big
effect.  For example, the emergence of Protestantism could have been
the result of the same accumulations of traits that Clark thinks were
selected in England.  (Clark might have discussed this in his book.)
I was motivated by the recent discussion on running the Huguenot out
of France to read the wikipedia page.  It was an economic disaster
when they were driven out of France.
