Is the government of Oceania an oligarchical collectivism? oligarchy = rule of a few; collectivism = everything is owned by the collective community...

As far as we
know, the government and society of Oceania does conform to these definitions pretty
well.

The government is probably an oligarchy.  We do know that the Inner
Party controls the major decisions made by the government (although we are not really clear as
to what role Big Brother plays, if he exists).  It maybe, however, a bit iffy to call 6 million
people an oligarchy.

As far as collectivism goes, it is not completely clear
to me.  This is mainly because pretty much no one has anything that they can own -- there's not
much wealth.  However, we do know that the government runs pretty much everything, so there is
probably little serious private property.
