In 1974 Barnett wrote of Britain's economic crisis as a low-wage, low-investment and low-productivity nation:...the peculiar structure, history and attitudes of British trades unionism is—and has been for a century—largely, although not wholly, responsible for this dismal cycle. You cannot pay high wages unless you have already achieved high productivity. You cannot achieve high productivity unless the work-force is prepared to operate modern machines to the utmost of the machines' capacity. Yet for all the glib talk by trades union leaders about improving productivity, everyone knows that British industry is fettered by demarcations and other restrictive practices aimed at preserving somebody's "property rights" in a particular task...the necessary switch to a high-wage economy cannot be achieved in isolation, by the process of "free collective bargaining" (ie, extortion of money by menaces or force), but only in step with a parallel switch to high productivity and investment. Are Mr Scanlon's members—and other British workers—prepared to match the efficiency, flexibility, cooperativeness and zeal of German workers—or do they really simply want more money for going on as they are?
