The Centre for Labour Market Studies (CLMS) in Boston says US unemployment is now 18.2pc, counting the old-fashioned way. The reason why this does not "feel" like the 1930s is that we tend to compress the chronology of the Depression. It takes time for people to deplete their savings and sink into destitution. Perhaps our greater cushion of wealth today will prevent another Grapes of Wrath, but 20m US homeowners are already in negative equity (zillow.com data). Evictions are running at a terrifying pace.
