Why do "some" young people in the Arab/Muslim world and even in the West find the appeal of terrorist groups like ISIS so alluring? Could it be because for the younger generation they see no hope for jobs in their future? As a result they become "true believer" fodder for an anti-western jihadist ideology.
The young of many Middle East nations are trapped in autocratic regimes like Saudi Arabia and Egypt where the "revolution of rising expectations" is met with a reality that hope for a secure economic future is simply not a reality. Hope is replaced by dispair and with dispair comes a potential terrorist recruit.
When one combines this with the three track class system in these nations - a rural peasant class with very traditional religious values, an educated urban class without job prospects and the offspring of the 1% who can live off the largess of their families - you get a combustible mix which becomes fertile recruiting ground for groups like ISIS.
One sees little effort by the US or our allies to address this problem by bringing economic development to this region.
"....the continuous single biggest driver of the kind of criminal Islamist extremism we see in the IS phenomenon is the predicament of several hundred million individual Arab men and women who find — generation after generation — that in their own societies they are unable to achieve their full humanity or potential, or exercise their full powers of thought and creativity, or, in many cases, obtain their basic life needs for their families..."
