Economists are awful people - they think they can reduce everything to dollars and cents.
Actually that particular slur is more aptly aimed at accountants. Economics is much more that the study of the next movement in interest rates, though that's the reason for the life-form known as bank economists. It is about the study of social behaviour, the choices we make and the inevitable trade-offs we face when preferring one thing over another. One of the points of confluence between psychology and economics for instance is identifying what makes people happy or satisfied. In this sphere a series of US and European surveys over the years has identified the drivers of happiness.
