Martin Kettle is right that the idea of a moral economy, first developed by the historian EP Thompson in respect of 18th- and 19th-century England, remains powerful (Liverpool football fans have shown why we need a moral economy, 12 February). For Thompson it was about a fair price for bread and beer, but today it focuses on a wider range of issues such as large corporations paying taxes and those in vital jobs such as junior doctors getting fair treatment. It is of course about the exertion of mass moral pressure, but for Thompson it was not some kind of fluffy protest. If the moral pressure didn’t work 200 years ago, the crowd would move on to what he described as “collective bargaining by riot” to make sure their voices were heard.
