Attempts have been made; I don't know of successes. Then again,
   through systems of taxation _some of this_ is true, especially
   in areas of high taxation; taxes are automatic and take care of
   basic needs.

   But they still depend on individual contributions into the
   system as far as I know.

   For such a system to work, it would require income to be handled
   solely by the State. Would its citizens be satisfied? That's
   where it gets rough.

   Small scale levels happen; intentional communities of various
   kinds and such have done it; I use monasteries as a strong
   example of this type of thing as they're the most well known of
   the Epicurian friendship communities, which can include shared
   "family style" expenses.

   But on larger scales? I don't know. I'd like it to be possible,
   if that counts for something.
