You are underestimating the power of religion and family. Besides moving away from Israel is hard enough, moving away from Gaza impossible.
Long term Israel has a demographic time bomb.
Given that the Israeli arabs and ultra religious are reproducing like crazy.
What happens in 40 years when 40% of Israel are Sunni Muslim and 25 percent are ultra religious (both groups which happen not to serve in the military)
Stuff is going to get weird, really weird. Laws will get weird. Case in point, recently they legislated shutting down all 7-11s on weekends in Tel Aviv, the secular heart of Israel.
Personally I ran away from the madhouse, but I had the luxury of being able to do it being Australian born. Many others do not. And many that can do not want to tear away from their family.
