The Communist Manifesto was written 160 years ago. long life expectancy, antibiotics, air travel, atomic bobs, mass communication with pocket computer, global population explosion, and countless other things didn't exist.
Referencing it beyond anything that summarizes what makes an interesting read is silly. Such silliness is right up there with using the "Holy Bible" as a soothsaying device prognosticating the end of the world and the second coming of Christ...which incidentally was a trend that began about the same time frame when the Marx wrote his masterpiece.
Its right up there with people still referencing Orwell's 1984 ... when in the actual year of 1984 the yuppies were wearing London Fog trench coats and financing the Contras against commies by snorting copious amounts of cocaine... as Nancy was saying "Just Say No"... seriously.
All those books have one thing in common... they strike a nerve of familiarity contained in the human condition... but then so does about anything Shakespeare. They predict nothing... so stop using them as some nefarious material to bolster your stupidity and in this current world of capitalism while insisting that capitalism should not be reformed and kept up to date to meet the demands of a changing world.
