....It's a modern, capitalist invention to divide the overwhelmingly large group of the "working class" and to rob them of their class consciousness.

There is no class consciousness !...lolol - it's yet another concept, trying to take on the qualities of reality.
....the purpose of which, is to divide (and control) - it also allows the low IQ useful idiots to think that they actually understand how things work, using simplistic, abstract concepts of 'class'.
Only the seriously cognitively impaired could ever accept 'concept' as 'real'.
(or the mentally ill - delusion is seen as a mental illness)

'Class' is an abstract, indefinable, idea.

One that's used by psychologically manipulative people wishing to create a divide where non exists.

By doing this , it also helps to perpetuate the 'poor me'- or 'victim mentality' psychology.
This enables the 'rage at the self' to be displaced outwards (projection) .
This external projection then allows the useful idiot to blame any external source for there self hatred (and poor understanding of reality).

...Idolizing marx as some kind of 'intellectual' - rather than seeing him as the social parasite and grifter that he was - is a good indicator of an individual with a poor understanding of reality.

Respecting a sexual predator, an abuser of women, and financial parasite - while espousing his works as some 'deep and meaningful' tome - says far more about the gullibility and naivity of the readers of his idiotic, low IQ rantings,than it does about the author...
