In Israel it is almost never happens that there are shidduchim betwen different groups and even sub-groups (e.g Ashkenazi and Sepharadi Chareidim, Lithuanian and Chassidic, etc.). I think that his is simply because there is such a wide choice that people can be more choosy.
In the political arena there are some tentative moves to unite the Chareidi and Chardal camps. The social and economic differences are also lessening as more Chareidi men are going into the IDF (albeit in Chareidi frameworks) and into the general job market (usually but not always in Chareidi frameworks). I heard from Rav Yeshayahu Steinberger in the names of both Rav Kook and Rav Soloveichik that this is the union of Yosef’s stick and Yehuda’s stick (Yechezkel 37:19). Yosef represents involvement in the general society (Mizrahi) and Yehuda, who established the settlement in Goshen, represents the establishment of a state within a state (Aguda).
