a shift to bourgeois values and practices
About the word:
Embourgeoisement almost always refers to a shift by the working class, not the upper class.
The word was coined during the first half of the 20th century, when scholars noticed workers adopting the outlook and behavior of the middle class. For example, the new bourgeois might have a declining interest in class consciousness and an increased interest in seeing gradual, not revolutionary, changes in society.
