"The Labour Party has been peculiarly disabled in the last ten years because so many of its own members have written off its history. Thatcherism was in practice distinctly vulnerable to attack – but not by a party which had denied its own past. How people choose to ‘remember’ the Wilson and Callaghan governments is consequently something to which the Labour Party should urgently attend: only if they ‘remember’ them benevolently (or at least not malevolently) can Labour hope to re-establish itself securely as a governing party. Yet there is still no evidence that the Labour leadership wishes to attend: on the contrary – as Mrs Thatcher did with the Heath government – they seem either to pretend that the Wilson and Callaghan governments did not exist or that they were mistakes for which the Party must endlessly atone."
"If an ideological alternative to the Conservative Government is to be made acceptable to the electorate, both folk memory and the Labour Party will have to change their minds about the 1964 and 1974 governments and the Labour Party will have to do it first. The Labour Party has committed the cardinal rhetorical error of any political party by apologising for its own past: the Conservatives may ignore their own past, but they never apologise for it. Labour has done this partly because of the utopianism of many of its activists – to them the best is always the enemy of the good – and partly because of a certain timid and innocent defensiveness. Labour always plays the game by other people’s rules. A measure of this defensiveness is the extent to which the Labour Party is happy to be thought the ‘caring’ party but is plainly less happy to be thought the ‘competent’ party, even though there seems no logical reason why it could not be both. It thus apologises for the Wilson and Callaghan governments because the activists said they fell below perfection while those in economic and cultural authority said they failed. But there are entirely adequate justifications for these governments which the Labour leadership should start making. Although it seems scarcely possible, the majority of the electorate still believes that the Conservatives are more ‘competent’ economic managers than Labour, and this basically means that they think the Tories are more fit to govern. We can be fairly certain that as an election approaches this belief will become more intense – much to Labour’s detriment. The Labour leadership must, therefore, assert that the Wilson and Callaghan governments were more ‘competent’ than their predecessors and successors, which they were, and sound as though they mean that as a compliment, and also recognise that their policies, though indeed imperfect, were better suited to a sluggish, rather uncohesive society than the alternatives. They might then be able to argue that the rather rough-hewn social democracy with which the Labour Party is historically associated has worked very much more in the national interest than anything else we are likely to have. And that we are more likely to have a productive capitalism under Labour than under its principal opponent. A Labour Party which restores itself to its own past might, having perceived its strengths, accept its weaknesses: namely, that under our present institutional and constitutional arrangements its spells in office may be fitful and unrewarding."
If you read the rest of the essay or other writings by McKibbin it is quite clear that he isn't a Blairite (or Brownite) by any stretch of the imagination. As such, perhaps someone ought to send every Corbynista a copy of this essay to illustrate their folly in repeating the mistakes of the last generation by denying the many great achievements between 1997 and 2010.
