Myth: Thatcher destroyed British manufacturing

The Myth

Margaret Thatcher's policies destroyed British manufacturing industry.

The Facts

Manufacturing output increased by 23% during her premiership. Manufacturing's share of GDP fell because services grew faster — but the absolute output of British manufacturers rose. Productivity per worker grew at one of the fastest rates in the OECD over the same period.
