Not having the resources to eke out a living isn't insignificant to them. It radically alters their social fabric. For instance, the act of maturing into a man from boyhood requires getting married. The boys can't get married unless they have an apartment built atop their parents' home. Without the resources to do that, you have a lot of young men who don't feel that they can achieve life goals. And isn't that the very thing that encourages extremism in other Middle Eastern countries? Warlords offer money and goods to their families if they sacrifice themselves through a suicide bombing. I think these are parallel occurrences. One that is just now boiling up, while the latter has occurred more and more often in the last decade or so.
As for thinking that Marxism battles religious discrimination, I don't think it necessarily will. The more important thing, first, is to enable these people to earn a living. Then after that is taken care of, maybe solidarity across workers, opposed to a single enemy, could begin to overcome ethnic strife. It has happened in the past.
Disclaimer: I'm neither an expert on Egypt or Middle Eastern studies, but I have made out with a PhD student who researches the subject.
