Businesspeople still enjoy huge advantages from being in America. Business is part of its DNA in much the same way that la dolce vita is part of Italy’s. American has a disproportionate number of the world’s most innovative business, from greybeards such as 3M to toddlers such as Salesforce.com. And Americans are to management what Brazilians are to soccer. After studying 10,000 firms in 20 countries, Nicholas Bloom of Standford University and three other academics concluded that American firms are the world’s best managed, with German, Japanese and Swedish firms a short way behind and Chinese and Indian ones trailing badly.
