Split between UTJ and Aguda

UTJ wants to join the coalition and accept the 500 shekel a month increase for families with 4+ kids. Aguda disagrees and wants everything restored, otherwise they won't join. Why is there this split? One theory is that the Chassidic Rebbes like the Gerer Rebbe have Chasidim coming to them all the time (every day) and fully understand the dire financial straits their Chasidim are in. They are close to their Chasidim and therefore understand what they are going through. On the other hand, R' Elyashiv and the other Roshei Yeshiva don't really meet with the average Kollel guy and therefore don't feel his pain. People don;t cvome to R' Elyashiv and complain that they can't pay their bills. Therefore, their opinion is a more theoretical one while the Rebbes are responding to their Chasidim.
