> educated students, doctors and engineers are joining IS

How many are? Do we have any good information on this? I doubt IS releases the professinal and educational backgrounds of its hires!

Generally, my impression is that historiclly the middle class has provided the idealogues; the theory is thhat if you're living hand-to-mouth you have more immediate worries and less time to study such things, and if you are illiterate you have other obstacles. That's just one possible but commonly repeated hypothosis: I don't know what basis there is for it.
