This book has a lot to comment on -- too much for a little post like this. Mainly, the distributions of capital, income from capital (and its rates of return), income from labour (and its rates of increase), the general growth of the economy, the differences between them, and their long term historical trends, and the political consequences of these trends, is carefully examined, and various policies for dealing with the problems these give rise to, are advocated for. The writing, or probably just the translation, is rather flat and dry (its certainly nothing like A. Smith), but it serves its purpose. I found frustrating the constant reference - in the notes! - to go to the online technical appendix, especially near the end of the book.
