This process originated both from personal frustrations among the kibbutz members as a result of internal processes and from the growing stratification and inequality due to the growth of capitalistic practices.[13] Over the years, some kibbutz members established professional careers outside the kibbutz, accumulating power, privileges and prestige.[14] The balance between individual values and values of the kibbutz began to tip, and work motivation was affected. An emphasis was placed on social compensation to encourage productivity."

Basically, the kibbutz was destroyed because capitalism still exists. Like the example of the Tiaga above, a utopian concept implemented within the larger context of a capitalistic society is doomed for failure.
