Islamic-inspired terrorism draws a direct lineage from the writings of Sayyid Qutb (https://en.m.wikipedia.org/wiki/Sayyid_Qutb), an Egyptian civil servant who studied in America and was aghast at how consumerism subversed communal and religious virtues, and even more shocked to see the same transformation occurring in the Arab world. He eventually drew the conclusion that consumerism sequestered people away from reality, and so he came to advocate for terrorist attacks on civilians specifically to force people to look at and confront what he perceived as poisonous Western values.
To say that all those poor misguided young men just need jobs and money misses the point entirely. The problem is with society itself. They yearn for an alternative, but we in the West are too much a part of the system to imagine life outside of it.
