Possibly, but Bin Laden wasn't the one with the bomb strapped on. He was more akin to a king sending peasants to die.
It is a fact though that lower economical areas have more crime and less opportunity. It would be harder to recruit the foot soldiers. It will always be the plebs that have the power to continue or end it, and one way they might choose to end it is because they have a comfortable life.
Look at Brazil, the inequality there, on the lower end human life means nothing. In conditions like that crime, terror, desperation will make people do anything to survive.
While I agree this ideology is different, most strong ideologies arise out of a lack of economic options.
If suddenly your house got bombed, members of your family died, and you lost the ability to survive economically, you'd probably survive however you can even if that means blowing something up for money for your family. People aren't born suicide bombers or terrorists, the environment around them forms that.
I am simply saying one known way to win hearts and minds is to help economically and give options to people susceptible to it. I am not saying poor people are terrorists, I am saying terrorism (or at least desperation crime) can grow in lower economical areas for recruiting more easily, and the only way to combat that is with better economics and opportunity. The same happens in inner cities with gangs, high unemployment etc. [1][2]
Equally decisive in determining crime rates are the more invisible barriers to crime set up by social norms and social cohesion. Indeed, one of the most robust statistical patterns known is that crime rates tend to go up with rising economic inequality, which itself tends to go along with erosion of social trust.
