I am going to plug a book I am not in:
John McDonnell has not forgiven me for once criticising Corbyn. That is his right. But many of the ideas in this book are familiar on this blog, even if there are also some I disagree with. Some issues discussed are, in fact, core themes here, from the Green New Deal to corporate tax reform. It would be churlish not to say that it's good that such things are getting the attention they deserve.
