What you say is simply not true - we know this because the fundamental measure - concentration of wealth - is continually increasing. Intergenerational mobility, particularly at the very top, is interesting, but ultimately irrelevant to most people. What is relevant are the vast quantities of people who suffer from poverty and grotesque inequality. Imagine explaining to some homeless person that society was pretty fine actually because in several generations somebody will have overtaken Bezos. Put another way - you don't make an unfair ladder fair by rapidly re-arranging people on it as much as possible (aka "social mobility" or "opportunity") you make it fair by flattening the ladder (inequality reduction) and making the bottom of the ladder a less unpleasant place to be (poverty reduction).
