I lived on a Kibbutz in the 70’s. It was supposed to be an egalitarian paradise based on the “each according to his needs” ideology.
Turns out, like every endeavor into socialism, the minute someone is put in charge Socialism becomes Communism. Then the inner circle become the haves and the rest become the have-nots.
Nothing mysterious here. It is just a fact.
And as I understand it, some Kibbutz were more favored by the government than others.
If an experiment fails time after time, there is something wrong with the equation.
