A kibbutz is a collective farm in which all property, except specified personal possessions, is collectively owned. Planning and work are collective, and collective living is the rule. Each member works according to his or her ability, and goods are distributed according to work. The land is held in the name of the Jewish people by the Jewish National Fund and is rented at nominal fees on long-term lease.
The kibbutz days are gone, now they just force-grabbed chunks of Palestinian lands built settlements and walled them as we can see from the above map. The Persians should not have liberated them from Babylon then they would be forever wandering.
