Letting the blighted in, though, is thought ill of by the good folk at the Home Office. Since the 1968 Commonwealth Immigrants Act, whose passage Michael Dummett calls "the most shameful act of any British government since the War", ingenuity has been persistently deployed in shifting goalposts, prompting officials to ever-sterner rulings, and muddying the language so as to conceal from ourselves the cruel shabbiness of our policy. (Rumours that the Palace Theatre has been asked to rename its long-running musical Les ?migr?s Financiers are, however, unfounded.) Our society, we are told, is built on family values, by which is meant the value we set on our own little platoons; we'll do everything for our children, and that includes preventing the wretched of the earth from doing anything for theirs, at least within the frontiers of our United Backyard. Though the cant of "globalisation" and "the death of distance" is widely intoned, labour is one factor excluded from the "borderless economy", except when it suits us to cherrypick teachers and nurses from lands whose natural resources we have a tradition of despoiling.
