The economic theory of rational choice was accepted for decades as a general theory to explain human behaviour which other social sciences lack. This paper reviews some limitations of the former. Through cognitive psychology, the paper describes the cognitive biases of people when assessing data and making choices, which puts into question the idea that the human mind is programmed to follow the assumptions of rational choice. On the other hand, the increased risks in modern civilization (monetary, ecological, geopolitical) and their global character define our society as "the society of global risk". The author discusses the limits of our rationality in regard to making choices as a troubling issue for coping with increasing global risks. [ABSTRACT FROM AUTHOR]

In this paper, I will show how the tendency to a bigger growth of capital than the one of the overall economy has generated an excessive inequity. I will also show how this is linked to a regression in the welfare state and the transformation of the citizen into a producer of goods and a consumer. I will try to show that this situation contradicts the principles of protection of the social and economic minimal conditions stated by the Universal Declaration of Human Rights and how international capitals influence political decisions and how it helps to transform the traditional concepts of sovereignty and citizenship. It is then evident that it is necessary to make political decisions to impose taxes to capital in particular to the international one. [ABSTRACT FROM AUTHOR]
