That is in the FT, here is the closing paragraph:
In most other ways, Cowen’s thesis is deeply troubling. Democracy requires growth to survive. It must also give space to society’s eccentrics and misfits. When Alexis de Tocqueville warned about the tyranny of the majority, it was not kingly despotism that he feared but conformism. America would turn into a place where people “wear themselves out in trivial, lonely, futile activity”, the Frenchman predicted. This modern tyranny would “degrade men rather than torment them”. Cowen does a marvellous job of turning his Tocquevillian eye to today’s America. His book is captivating precisely because it roves beyond the confines of his discipline. In Cowen’s world, the future is not what it used to be. Let us hope he is wrong. The less complacent we are, the likelier we are to disprove him.
