&gt; educated students, doctors and engineers are joining IS<p>How many are? Do we have any good information on this? I doubt IS releases the professinal and educational backgrounds of its hires!<p>Generally, my impression is that historiclly the middle class has provided the idealogues; the theory is thhat if you&#x27;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&#x27;s just one possible but commonly repeated hypothosis: I don&#x27;t know what basis there is for it.
