This book is uneven as the chapters cover various subjects with greater or lesser insight.
The first short chapter, a narrative account of the global financial meltdown of 2007-09 from a Marxist perspective, is good.
The second chapter, which gives a macro-scale account of the global economic developments of the 'neoliberal era' that presaged the 2008 crisis is very good. It's superior to most major 'Marxist' alternatives, including for example David Harvey's - particularly as it shifts the analytical lens from weak concepts like a 'neoliberal thought revolution', generic 'financialization' or 'spatial fixes', to more concrete issues of political economy: the real ruling class dilemma of the stagflation crisis of the '70s as being rooted in the contradictions of Keynesianism, a global crisis of profit rates, and increased real capitalist competition between the big industrial economies, among other factors.
My favourite chapter was actually the third, which is really just an overall introduction to key concepts in Marxist social thought: its micro-sociology of capitalism and class conflict, the accurate 'Political Marxist' historical account of its origins that draws on Marx's writing on 'primitive accumulation', a useful summary of Marxist crisis theory and its superiority to rivals such as Keynesianism, and the various political and ideological conflicts systematically generated by capitalism's dynamics and constraints. This chapter is really just an excellent up-to-date primer on theoretically accessible-yet-rigorous and empirically-grounded contemporary Marxism, and should be a must-read both for anyone teaching or researching in the social sciences, as well as leftist activists.
The final chapters are sort of broad overviews of questions of racial domination and political resistance to the neoliberal era. These were pretty lame and skippable. McNally has a tendency towards a vague hippy-ish idealism when it comes to tackling real questions of politics and working class re-formation - there are better alternatives out there that don't really on some never-going-to-happen rainbow coalition of NGOs, peasants, workers, union bureaucrats, race/gender entrepreneurs, unemployed, etc. In particular the analysis of Kim Moody and Charlie Post is much better in situating a more grounded account of the dynamics that could impel the re-emergence of the only social force actually capable of challenging global capitalism: a militant rank-and-file labour movement in the industries of the capitalist core.
Basically, the third chapter is worth the cost entry alone, while the second chapter is one of the better accessible long-term/macro introductions to the analysis of the 'neoliberal era' (1970s-2008) of capitalism. The rest of the book is solid but average.
