every time this film be on the bbc somebody in the radio time say how it be a satire against the post war world of ration and the welfare state . i do not think this be the point of the film at all . the film parody the spiv ( small time criminal who run the blackmarket ) and the housewife league who campaign against government restriction but be really a tory front organisation . yes of course the film send up the political or social situation but in the end the people realise that they need all the control to ensure a fair society and they want to be british and muddle through rather than foreign . but i do not think they go back to be exactly like they be before .
