Maybe... perhaps even the concept of different social classes was also created by us
because some idiot or another thousand decided that they were better than others, the whole hierarchy was constructed to reinforce this originating thought.
I think that if all (or at least a majority) of us can see right through it all and call bullshit on the class divisions,
then we can overturn it and create a better history for future generations to come.
Well, what you're describing is a philosophical idealist's conception of social class, of anything really, it all goes back to Bishop Berkley's idea that everything is a figment of the imagination or product of the mind.
Marx is only one materialist, there's also other sorts of skepticism which are materialist too, probably the greatest challenger to Marx, which I think wasnt talking nonsense was Max Weber, who argued for culture, or rather religion and ideology, having a role other than reflection of ruling class interests, the development of the means and mode of production in any epoch etc.
The truth or reality is liable to be some complex integrative theory which combines the best of Marx, others of his ilk, and other sociologists like Max Weber.
Just in relation of class divisions, I dont think its possible to eradicate them entirely, though there are marked differences between how they manifest one society to another, and those that are not marked by class struggles, have some sort of transcendent or emergent harmony or consensus instead, are more prosperous.
