The basic dynamic is same. Instead of powerty, muslim extremists are fighting perceived corruption and immorality. And instead of future socialist paradise, they're fighting for paradise in afterlife. Same cat under different fur pattern.
The similarities between communism and Islamofascism end there.
You might be right in a certain way, though: capitalism and wealth, while not directly antithetical to the root causes of Islamic extremism, certainly offer an excellent alternative to it. Several notable exceptions aside (OBL, Patty Hearst, although she's kind of a special case, having been kidnapped and all), people don't blow themselves up if they've got good jobs and live stable lives.
Of course, most of your cocktail-chuckers are teenagers or early twentysomethings, especially in France, occasionally too young to be considered "adults" and care about that sort of thing...
