Reversing Britain's long-term economic decline. That was the daunting task Margaret Thatcher set herself when she arrived in Downing Street in May 1979 at the end of a traumatic decade that had seen a three-day week, inflation topping 25%, a bailout from the International Monetary Fund and the winter of discontent.
She gave it her best shot. The last remnants of the postwar consensus were swept away in the ensuing decade – a period that saw the crushing of the trade unions, the Big Bang in the City, council house sales, the privatisation of large chunks of industry, the encouragement of inward investment, tax cuts, attempts to roll back the state, a deep manufacturing recession, a boom in North Sea oil production, and support for the creation of a single market in Europe.
As far as her supporters are concerned, this radical transformation worked. Britain ceased to be the sick man of Europe and entered the 1990s with its reputation enhanced. The economy had become more productive, more competitive and more profitable. Deep-seated and long overdue reforms of the 1980s paved the way for the long 16-year boom between 1992 and 2008.
To her detractors, Thatcher is the prime minister who wiped out more than 15% of Britain's industrial base with her dogmatic monetarism, squandered the once-in-a-lifetime windfall of North Sea oil on unemployment pay and tax cuts, and made the UK the unbalanced, unequal country it is today.
The truth lies somewhere between these extremes.
