Israel is simultaneously struggling with a growing lower class in the shape of their ultra-orthodox, the Haredi. This group has a large growth rate coupled with an uninterest in taking jobs that are not scholarly. Couple this with the fact that they are exempted from military service unlike all other citizen and you have a large source of internal tension. This would only be an Israeli social problem if it wasn't due to the alarming fact that the Haredi are also typically hardliners when it comes to Gaza.
