And which is the ‘real’ market of the Financial Times?
That said many areas of finance might in fact be truly unproductive, for instance I harbour serious doubts on the validity of much of the financing of consumption; and much of the financial innovation, although perhaps valid in principle and theory, has resulted in disasters that makes it obvious that we need to reign our tendency to give any innovation the full benefit of doubt.
The Financial Times does a lot better defending the financial sector when it points to the real connections between the financial and the other sectors of the economy but, if that results in a shrinkage of the financial sector so be it, that in itself does not mean it is bad.
Finally your humble acknowledgement that “finance is riddled as it is always has been, with gamblers using other peoples money, chancers taking risks but calling it genius, and worthy people following the crowd into collective insanity” but completely leaving out the regulators who with their excessive empowerment of the credit rating agencies laid all the foundation for this crisis has nothing to do with “Without fear and without favour”. Perhaps the Financial Times needs to reflect a bit more on its own real market.
