What stands out in the book, is that an attempt is made to set out the propositions set out on the basis of a broad data. The author uses this, particularly on control data of the tax offices, which are examined over the entire available period. This allows for the first time investigations over prolonged periods. Based on the analyzed data is a serious analysis of the growing inequality in income is made, which is very interesting inasmuch as the attention is drawn to facts that are not fully compatible with the prevailing opinion. The attacks on the book (including that of Chris Giles in the Financial Times), who deny or sugarcoat the growing inequality and justify, although the data clearly prove especially since the 80s of the last century and this even under a historical perspective quite conclusive, seems thus tapped and dull. The reviews thus seem rather a dusty ideological debate (which is reminiscent of the Cold War) to attach as an effective scientific discourse. The fact that the book is aimed at a broader audience and not solely to the professional world and the author therefore seeks to facilitate the understanding of this wide audience in order to stimulate a policy dialogue on the issues raised, can by no means an indication of a lack of epistemological coherence of the book be considered, but rather as a were sticking the book. This continental science often strange clarity is fully in the Anglo-Saxon tradition of science, in which the authors laudably strive also to simplicity and clarity and does not rely on the cryptic language less initiate. The book thus has a certain literary quality and is also linguistically appealing. In summary therefore be said that the book is highly recommended, if only because of its originality. Personally, I have already passed on it as a gift.
