In the 1950's there was an element in HaShomer HaTzair that opposed the Moroccan immigration as they did the remnants of Auschwitz, because they had not experienced Hachshara. Ben Gurion shot them down both times, much to his credit. One should, however, take note of the fact that almost singularly among countries that had Jewish populations, Morocco never had a Zionist movement, and therefore, never understood what Israel was all about. In addition, all Moroccans that $20 or a 4th grade education went to France or Canada. Israel for the most part got the under-achievers. Ben Gurion didn't turn his back on them and their integration will be complete when, like every other ethnic group, they stop talking about "Caza" and decide to contribute to the country. This is a chore for all of the aliyahs and native born Israelis, the Moroccans only started with more of a disadvantage. Don't blame the Ashkenazim for this.
