I have had enough experience in and around the upper reaches of companies to know that their kind of Oxbridge cleverness is, except in the smallest of doses, surplus to requirement. What’s needed is shrewdness, judgement, an ability to concentrate and, most important of all, a mastery of the possible. If you follow the thesis of this programme we arrived in the present pickle thanks to a load of clever people in business who thought they could change the world by moving a few columns of figures. There’s some truth in that. What’s even more worrying is that the clever people in government purporting to be able to get us out of it by a little quantitative easing here and the postponement of a few spending projects there know even less about how the real world works. I think they’re all about to be found out.
