Well cities are often cesspools so I can see how a group descended entirely from affluent urbanites could have a lot of negative, culturally entrenched baggage.
You say 'selected'. Do you mean in terms of genetics? Of course I'm willing to accept IQ being inherited genetically, and I'll even grant you 'neurotic', but I'm not sold on 'greedy' and 'manipulative' being hereditary traits (if that's what you meant).
I think of ingroup preference as something that most groups have, only it's beaten and shamed out of the ones that aren't allowed to have it. But it's very plausible that being kicked out a bunch of countries and developing a 'it's us against the world' mindset would kick it into overdrive.
But it's an interesting theory, thank you for sharing it.
