It is important to understand the Kibbutz
in context. As a self-reflecting
local, it seems evident to me, considering the results of the Kibbutz experiment, that it was never intended to be a successful experiment.
By that, I mean that it was
never a real experiment. The Kibbutz was a strategic way, for those in power, to claim the lands that were either previously occupied by Arabs, or that were under contention, without being actually occupied. Once you had young zealous people taking over a place and running it, it was not likely that they would fail to continue owning that
land, nor rebel against those in power (due to having newborn children.)
The strongest case for this idea is the fact that quickly
enough, once Israel was based, the government prevented any more new settlements and turned to using army bases to defend their interest.
This is the current situation in Israel. Those previously agricultural "free" lands are now rapidly being converted into industrial development areas, for
profit, with disregard to the needs of the population. This new industry includes, by the way, agriculture and houses, more than anything else.
So, the
conclusion here is that the Kibbutz was never an independent effort with independence in mind, but rather a
government financed and coerced effort, with the one goal of immediate occupation, then followed by extortion and return of the land back into the government hands (in the guise of industry.) To clarify, this means that the Kibbutz was never meant to be
sustainable, as it was always protected by the government and rich.
