The Financial Times carries a story in the King Kong Vs Godzilla vein. Wal-Mart, the world’s largest private employer, is jumpy about the arrival of Tescos, the UK’s largest supermarket chain, into the US market. The Walton empire is pondering how to develop new ‘Wal-convenience’ stores, along the same lines as the smaller ‘Tesco Extra’ stores in the UK, to fend off what is likely to be a very aggressive push from the UK firm. But just like the old Tokyo disaster movie, regardless of whether one or other side wins, the battleground is home to millions of ordinary people, whose architecture and lives are likely to be severely remodelled in the deathmatch.
