Done now with Pikkety. Well, he summarizes it very simplified. I think his model doesn't necessarily mean that the person who was rich 10 years ago is richer now. It still works out if for example each year a start-up of the same size has a 5% bigger exit than the year before, but 10 years later the founder of the first exist is broke and homeless already. What I mean is it doesn't, afaik, consider fluctuation in each group. Also many economists criticise that money is only measurment of wealth, and some are quite hard to represent in $.
