It is the last taboo. Talking about it is not something a nice girl does in mixed company, it is indelicate, unfeminine. Many women have been raised to believe that men are "naturally good" at money matters and women are "naturally bad" at money matters. It's not said directly, little girls pick up this idea by osmosis. Outside the home, for a man to say he wants more money or ask for a raise is acceptable; it goes with the hairy chest and the company car. But women can't say that, they won't even admit it to themselves and they don't want to think about why.
In a time of economic austerity it is hardly surprising that public opinion has turned to those receiving benefits from the state, particularly those who do not work. Repeated stereotyping and manipulation of statistics in the media have painted many of Britain's poorest citizens as lazy good-for-nothings living a life of luxury at our expense.
