It's not the best explanation of the actual socioeconomic theory though, it was written more as a political ad, if you will.
If you're more interested in the actual theory, I'd recommend Foundations of the Critique of Political Economy [0].
In that book, these are particularly relevant:
The introduction
This is basically a systems thinking level analysis of the economy and a good primer.
The note about machinery, production and capital [1]
This talks pretty much exactly about machines increasing productivity, the implications for the worker and even speculates about workers one day just becoming "regulators of automated systems".
(2) General relation between production, distribution, exchange and consumption
Talks about the mechanisms behind the "frenzy". Heavy on the philosophical theory.
