Encumbered by folly

SIR – In the current tumult of Brexit and trade wars, is it not apposite to quote from Adam Smith’s The Wealth of Nations (1776): “The natural effort of every individual to better his own conditions... is so powerful a principle, that it is alone, and without any assistance, not only capable of carrying on the society to wealth and prosperity but of surmounting a hundred impertinent obstructions with which the folly of human laws too often encumbers its operations.” Donald Moore
