The top five causes of conflict in relationships are money, sex, work, children and housework – in that order... The second episode in Vanessa Engle’s series Money examines what money represents within a relationship – and in the process explores the nature of marriage and long-term relationships. How do couples agree on their financial priorities? Do the rich argue less about money than the poor? Is a joint account an indicator of emotional health? The film features a broad spectrum of couples from different backgrounds – where one person works and the other doesn't; where one earns much more than the other; where one person is extravagant and the other is frugal; where one is a saver and the other a spender. Each case sheds light on the extent to which money is a source of conflict but also the ways in which it oils the wheels of our intimate relationships.
