It looks like they copied the concept from a 2012 Forbes feature. It was 'repackaged' poorly cos I would like to know how GDP per capita/PPP translates to "Average annual income per person"?? Basic knowledge fail? What it does translate to is a clickbait headline I suppose, haha!
Sometimes it is good to feel great that you are rubbing shoulders with the world's 3rd richest nation's people. Then when you wake up from your dream, you realise 'Rolaxes, Leicas, Hermes and Louis Vitton handbags and an Audi in your garage' not there as promised by Sion.
Maybe we have just too many FT that we cannot differentiate the world 3rd richest group from the real citizens.
