The topic that I have decided to discuss in this article is the progressive imperialization of culture, the dehumanization of society and the phenomenon of Macdonaldization (combined with the adoption of the American lifestyle on many levels), which have an impact on the socio-cultural changes of the 21st century. It is a sensitive topic, because changes taking place in society are very dynamic, and the progressive commercialization of aspects of life affects our perception of the world and personal development. The article is typical from the border of sciences, interdisciplinary, and fits into the field of cultural and sociological studies. The article is divided into three short chapters devoted to: definitional and notional issues, the comparison of interactions of the discussed phenomena with the society as well as the author’s conclusions and observations. The work was based on the publications of other scientists and researchers in the field of the phenomenon of Americanization / Macdonaldization itself, as well as sociologists, economists, cultural scientists and cultural theorists.
