However - chicken <-> egg.

Markets are based on moral imbecility because the people who worked hard to define the ideology are vicious spoilt children. Naturally, their ethics reflect this - qv Bush who is the mushroom-like excrescence on top of a fungoid crap-fed culture of white-bread privilege that has infected the US body politic.

If Aspergers types find economic favour, it's a symptom of that fact, not a cause of it.

Marketista ideology is a direct result of a handful of rich crazies in the US deciding to create a shift rightward. It's been one of the most successful social engineering projects in the whole of history, because they've effectively created a huge propaganda edifice made of many bricks, all different, all apparently unrelated, pushing the same party line to create a compelling illusion of unanimity.

Traders have been happy to play along because the results benefit them directly.

But the fish rots from the head down. The savants and indeed many of the traders are useful idiots, not instigators. They'd be just as happy doing something useful, if something useful could possibly be found for them.
