This paper is an attempt to specification of the city, perceived not in a culturalistic (i.e.as text) but structuralistic way, by taking the example of inequalities that city aggregate on account of the existence of many different social entities. Human ecology was at first in explanation the consequences of inequalities in the space. Presently the structuralistic approach toward inequalities in the United States is maintained by the scientific schools, emerging from the “new urban sociology”. These schools recognizes the process of production and the circuit of capital as primary sources of differentiation and social tensions. They recognize the urban problems through the prism of global political-economical and the extensive social processes. From that point of view, urban inequalities are specified as the distance between “top” and the“ bottom” of the social structure, epitomized as dualism.
