We had to dispel the notion that the way to economic success lies through a sort of fiscal levitation. That was the abiding post-war delusion-that governments could spend and borrow their way to prosperity, and fine-tune the performance of the economy through something known pretentiously as demand management...It used to be an establishment nostrum that you need a budget deficit to get economic growth. That was the belief which lay behind the notorious letter by 364 economists in March 1981. We have given the lie to that, decisively. There can no longer be any argument about it. Everyone-or almost everyone-now accepts that the proper role of macro-economic policy is to keep downward pressure on inflation and to maintain a stable framework in which the private sector can expand.
