This is the recent Pluto edition of this famous pamphlet with the postface by John McDonnell. Took me a very long time to read this, as it came out when I was decreasingly convinced the left could usefully be 'in' a certain organisation, and while it doesn't deliver all it promises, a book Of Great Historical Interest. What's really happening here is post-1968 leftists, both middle class and working class, realising that they're working for the state, whether as bus drivers or social workers, and after some heavy breathing about why that's a bad thing (too much of the book is this) some very suggestive and provocative short theses about what they could do in it that could democratise and socialise how people experience "the welfare state". Some of the sections on how the public state of the time was lacking haven't aged well, typically; some of these seem like nice problems to have from the vantage point of the 2020s, albeit a little less so than in most books of its kind. The main problem is that the real interest of the book - the 'in' - takes up a great deal less space than the more familiar 'against'.
The McDonnell material is typically charming and interesting on how the GLC used the book in allocating funds and organising during the eighties, but the comments on the Corbyn era only made me recall that while the organisations that came out of that moment were hardly prefigurative and emancipatory in the way the authors of In And Against propose, they also lacked the hierarchical but predictable and easily understood chains of command and means of appeal of an old-school Fabian/Morrisonian bureaucracy. In fact, Corbynite organisations and media were nearly all run like start-ups, moving fast and breaking things with opaque structures, charismatic but unaccountable figures at the top, and almost zero democracy of either a representative or participatory form; and 'defending Jeremy' or 'keeping the AWL out' won't suffice to explain why this was. Some day, people will write the assessment of all that, and where it got us.
