The "white collar" level is in no way immune to these mechanisms - indeed, they are far more like to go down the radical/terrorist path than the underclass, which usually lacks the acumen to channel their frustrations in such comparatively sophisticated fashion. The ghetto boys tend to engage in aimless violence, vandalism and rioting instead unless recruited by some suitable populist movement; the modern urban equivalent of Medieval banditry.

The leaders of radical movements have always had a tendency to be from the educated, middle-class or above layers of society. They have enough of an analytical toolbox to articulate their bitterness and anxieties into some kind of cause. Just for an example, most of the founding members of the Rote Arme Fraktion were very much members of the educati.

Same thing here. The truly dispossessed, such as the youths of the French immigrant ghettoes, manage little more than pointless street violence and huliganism to vent their ire. The British doctor becomes a member of a terrorist cell and starts building bombs in the Qaidaist fashion.
