Twenty-nine years ago, Margaret Thatcher stood on the steps of Downing Street and quoted the words of St Francis of Assisi: ‘Where there is discord, may we bring harmony. Where there is error, may we bring truth. Where there is doubt, may we bring faith. And where there is despair, may we bring hope.’ We know what happened next. There’s a lot of nostalgia for the music of the 1980s, but the social context was one of mass unemployment, the miners’ strike, the poll tax. And more homilies from politicians on morality, as if they were not the ‘broken society’ writ large.
