My best friend's boss is a Jewish carpenter. Literally. And when he's also a full-fledged commie, and went to Israel to live the socilaist dream in the kibbutz. Where he met his wife, who is a sabra (jew born in Israel).
I haven't talked to my friend's boss about the kibbutz experience/life, but I worked with his wife who waitressed in a restaurant with me. She said it was "a beautiful life". She was also an unabashed commie.
The kibbutz is dying. Israel was a communist country at first because there was the whole tribal thing to hold it together. That has changed. Israel's capitalizing and a lot of the kibbutzes have adapted to that. But the real thing that was revolutionary about the kibbutz was the destruction of the family/communal raising of the children. And the reaction in that experiment has been strong rejection by the children, who leave ASAP. It's basically is like growing up with hundreds of brothers and sisters.
Kibbutzes also had a really Marxist value system, where if you labored hard physically, you more valued than say, a school teacher. Based on the theory value came from labor.
