You don't need to have a copy by the desk, Larry - here's a copy on the net, in a computer in Colorado - Karl Marx and Frederick Engel's
MANIFESTO OF THE COMMUNIST PARTY

Remember, "Dictatorship" in this context means essentially the same as "Rule". A society where power lies in the hands of wealthy people, where wealth determines what goes in the media, and who is elected to positions of authority is in this sense a dictatorship of the wealthy.

The fact that there are divisions and disagreements between the wealthy as to how to use their power is a secondary matter, and does not alter the fact that they do have this power. That doesn't mean that those divisions and disgreements aren't important, but we shouldn't ever fool ourseleves into thinking that they comprise the whole range of options whuich we have as a society.
