I believe the GP is talking about the fact that most of the jihadi foot solders are unemployed/under-employed with poor job prospects, and many are unmarried with poor marriage prospects. For instance, Saudi Arabia for a time had a program where they took convicted jihadis, gave them job training and loans/grants for dowries (and maybe ran some kind of matchmaking service... I forget the details) and saw significantly lowered re-arrest rates for jihadis who got jobs and wives shortly after leaving prison. Improving economic outlook reduces the pool of recruits, but the GP is questioning the long-term macroeconomic outlook in the region, and in turn questions the long-term viability of harming extremist recruiting by improving job prospects for young unmarried men.
