Regrettably no, says Dalrymple. Sure, she helped to tame the unions, but their power was on the wane anyway. But what about her effect on government as a whole?
[D]id Mrs. Thatcher roll back the state, as it was her intention and indeed vocation to do? Here I think the answer must decisively be no. That is, at least if the question is about her long-term effect. It is true that she managed to reduce the public sector’s proportion of the Gross Domestic Product somewhat during her term in office. But 30 years after she entered office, it was higher than when she entered it. In 1979 it was 44.6 per cent; in 2009, 47.7 per cent. Her long-term effect (if 30 years counts as the long-term) on the size of the state was nil, despite her reputation as a prudent or even savage cutter of public services.
