Staying to "finish the job" has become the favourite excuse for failures clinging limpet-like to their jobs. Alistair Darling and Gordon Brown have both used the excuse in the last couple of days. And many of our failed bankers and other business leaders have used it before that.
At what point is the job of a politician or business-leader finished? Will Gordon, at some point, say: "OK. Job done. No need for a Prime Minister any more"? Does Alistair hope at some point to put the economy into such a steady state that we can do away with the role of Chancellor?
Or are they just cringe-worthy, lying bastards who will use any form of words to justify clinging on to power and privilege, believing (probably rightly) that a big enough proportion of the media and public are sufficiently gullible or apathetic that they won't challenge them on what a load of balls they are talking?
I suggest that anyone using this as an excuse for why they should continue in their job should be dismissed instantly for evident stupidity or insincerity.
