Perhaps I need to explain the joke for anyone who isn't familiar with old communist terminology. There used to be the phrase "socialism in one country." It meant that communist countries were supposedly self-sufficient. Hence, the humor of "socialism in one family" -- it describes in a few words how the Ceaucescus were a nation unto themselves while they looted Romania.
Chavez is doing the same thing to Venezuela. Old communists in the Old World and new communists in the New World are very much alike.
