english: So I've been working on the history of income and wealth distribution for the past 15 years, and one of the interesting lessons coming from this historical evidence is indeed that, in the long run, there is a tendency for  the rate of return of capital to exceed the economy's growth rate, and this tends to lead to  high concentration of wealth.
