The most correct book in the entire world. Read it whether you're a Marxist wanting to understand feminism better or (especially) a feminist wanting to understand Marxism better. The explanations of core Marxist concepts like surplus value, labour-power, necessary labour, and so forth are some of the most precise and accessible out there, while still making subtle but important new insights into how and where they work. The core of the book's genius, to me, is that Vogel doesn't take the easy way out by just looking at Marx's (and Engels' and Lenin's) failure to fully or properly theorise women's oppression and going "okay, I guess they have nothing to say about this, we gotta come up with something new." Instead of seeking to revise, rewrite, or contradict Marxism, she pinpoints something that was already inside the logic of Marxism (Capital, Vol. 1 in particular), namely the fact that labour-power is a commodity (with a use and exchange value) that must be produced and reproduced, and fully opens it up for analysis. The implications are absolutely revolutionary, and in the last few years people like Tithi Bhattacharya and David McNally have finally started taking it on and pushing it forward. While other feminists have tried (and, in my opinion, failed) to do this as well, in particular the autonomist feminists, only Vogel's theory actually holds up. This is because, rather than simply taking the Western nuclear family as a "social factory" and analysing women as essentially a "proletariat" within this framework (a very dogmatic, lazy way of shoehorning the economics of production somewhere it doesn't quite belong), Vogel produces a framework for a theory of social reproduction that can account for all the different places, contexts, classes, and social formations labour-power is reproduced.
