Well, it's not the system in Israel. It's not the system for Jews in NYC. There might be some splinter or small groups who live like that. Many in the LDS Church lived by the United Order in the 1870s. It actually helped the Church grow and prosper for a while but, like all earthly socialism, it failed because of outsiders coming into the communities, taking but not giving, and because of greed and competition just like in all other places things like that were tried. There were several other communist communes created in the United States, from the 1850s through at least the 1970s. There are probably some today. All of those that existed failed for the same kinds of reasons. All of those happening today will fail for the same reasons.
In a perfect world, when Christ rules the earth and the petty greed, jealousy, and other human problems fade away, there will probably be a more communal way of living in all of the world but it won't be communism as you know it because it won't be forced at the end of a gun and, under Christ's perfect example, the corruption you see today won't exist. People won't have to share with the poor because people will all work. There might be communal efficiencies, such as I grow a great big plot of corn and someone else sets up a lumber yard and then trades lumber for corn. But that's not communism; it's liberty. And the lumberman won't try to get all of the corn, and if I grow the corn, I won't require that someone give me more for a share of it than what is reasonable. But that, too, is not communism; it's compassionate sharing, trading, free trade even, but done honestly. It's the compassion, honesty, love, kindness, that causes communism to fail completely and definitely damages the success of capitalism.
So, no, Jews aren't inherently communist. Neither are any of the other groups who have tried it. Most, ignorant from lack of experience, truly believe that they can live better lives, dealing with others in a communal fashion. but, until the return of Jesus Christ, they will all fail. For those who do not believe in Christ - well, if you're right (you're not but we can pretend) then any kind of communal living will always fail in civilized society.
