In his latest article in Haaretz, the economist Avraham Tal repeats the usual security claims in support of the wall/fence but also gives another, supposedly more important argument. Tal argues that if a Palestinian state was to be founded in the future, the wall/fence will be instrumental in separating the emerging, probably poor economy from the Israeli prosperous one:
Meanwhile, at a distance of a few kilometers, sometimes merely dozens of meters, from that backward Third World country [the future Palestinian state], will be an industrialized Western welfare state that provides a high standard of living and whose citizens hold valuable assets. Such wealth will render incursions into Israel a ceaseless source of attraction. The agricultural robberies of the 1950s and car theft after 1967, and the invasion of 150,000 illegal residents since then, will be a mere preview of coming attractions for what can be expected as the gap widens between the standards of living in the Palestinian state and Israel in coming decades.
If an effective fence does not divide the two, life in Israel won’t be livable and a quick process of abandonment will begin. Whoever claims there is no need for nor point to the fence has in fact come to terms with Israel committing suicide as a Western Jewish state, en route to establishing a binational Middle Eastern state.
If the flow of poor Palestinians from their newly founded country will make Israeli life “not livable”, one can only assume that Tal agrees that the Palestinian’s lives in the first place would be even worse (and his article seems to corroborate that). As long as the Palestinians will be behind a wall/fence, and of no concern to Israeli privilage and security (in that order), Tal doesn’t seem to care of them or their existence.
