Do you feel Marx would see replication of the capitalist processes of his day, or would he adjust his vision of capitalism and conflict?
It is hard to say what Marx would have done, but it seems like his theories would definitely need to be adjusted to fit the very different capitalist system that we have now.
In his day, the classes were split fairly neatly between those who owned the means of production and those who did manual labor in their factories. Today, those distinctions have become blurred for many workers. We have a large white collar work force today that does not own its means of production but which is also not a laboring proletariat like the one Marx knew.
At the very least, Marx might have to posit a third class of white collar workers and look at how they fit in to and change the bourgeoisie-proletariat dynamic.
