Inequality, in its different forms, was putted in the middle of the political economy debate for decades. One of the main factors that influenced both sides involved in this debate, besides political orientations, stands the view of how the State interacts with the market e with the society. In Europe, on the opposite side of thinking about the more developed is a State the more its society is living in better conditions, in the last fifty years a decrease of all the socioeconomic indices was observed. That, although it is a very significant point in common among all the academic works, it is not satisfying for a deeper analysis on the nowadays European countries reality. Searching for the area s countries inequality factors, a tendency to change was observed regionally. That could suggests a common path for the countries of the same area, that has had leaded to same inequality indices. What was pointed out, although is yet a very prominent subject to be studied, it was just the beginning of a more relevant observation when common points suggesting closer clustering of income concentration and social mobility structure was found out. If Gini Index (the main index used to measure inequality) could be seen yet as a relevant factor to study socioeconomic evolution of those countries, it is even more profitable to link an analysis leaded by income polarization indices to this research, in order to see clearer what happened to the European countries, socially and economically speaking, during the chosen period. Founded trends thanks to this kind of analysis not just show us some peculiarities about the diverse politics used by different States, but also sets a time-laps of every single event in which, both on the international and national market, significant changes has happened as its consequence. With the goal of catching these king of changes of the European area, which ones were more relevant and how they can be explained for future understandings, this dissertation try to work as a multidimensional analysis about wider phenomena caused by international market and capital on the national plane. Following a critical theory that puts all that issues on a wider plane of investigation, a Marxian historical materialism analysis leads the main methodology of the research, as well as the analytical choices and sources to be used.
