It's true Germans have this very precise element to their culture. But where it lets them down is sometimes Germans cannot think outside the box and need indstructions to follow.
Recall that we in England used to be the world's foremost industrial power. Is the change economic, or cultural? Well, I do not subscribe to the theory that the English as a whole are lazy. Our full time workers work some of the longest hours in Europe, and work more and more overtime. But we have many part time workers who want to work more.
