Happyiness and wealth

Various lefty books over the last decade have claimed that wealth does not make us happier (Affluenza being the first one that comes to mind). They based this assertion on a study done which compared happiness levels between countries. Whilst the study did support this view, the data it used was limited. New studies, using much more data, have found money does make us happier - generally. Or, at least, there is a link between happiness and money, they just aren't quite sure which way it goes. What they do know is that the old theory was wrong.
