Around 18.5% with my meager trainee income, and... top 3.5% on possessions? On devaluated Brazil currency? WTF? Piketty was right, a lot if not most of money do come from inheritance, and that's just a portion my relatives transferred in life.
But then... maybe these numbers include the whole population of the world, not just working age, so I guess that could be why numbers seem so high.
