Policies on the threshold of the third Millennium still seem to be reluctant to decide between economic growth and social distribution. In our context a search for proportionating of the micro- and macro- worlds of politics cannot leave out such terms as for example a progress. It is not simple to prove whether objective progress does or does not exist. Even in early times of modernity philosophers knew well that a rational argument cannot be applied because scientific progress reasoning as a rational argument is part of science method. Social sciences deem it fruitful to search for fundamental contradictions when analysing social reality. When studying capitalism we must consider its raison d´être, the never ending capital accumulation. It is not simple to answer to the question why the modernity ideologists were promising what could not be fulfilled, why people believed their promises and why they do not believe them today. Thus the problem of rationality today is influenced by this situation.
