You consider one of the reasons to be the main and only unique. In more large social-culture contexe
you see the trend of inflation of the value of the education (clearly visible from the student riots of 1968 in France). Why do somothing if your education does not garantie to you automatically and immediatlyprestigious job, high earnings and higher social status?
This response doesn't seem to have anything to do with the question I posed. The student protests in 1968 France do point to a larger social-cultural trend of skepticism around the inherent value of education, beyond just immediate career and financial outcomes. The inflation of educational credentials is a complex issue with multiple contributing factors.
However, I would argue that the relationship between social media use and academic performance that I observed is a more specific and direct phenomenon, rather than being tied to those broader societal trends. In fact, there appears to be a more distinct dynamic between higher levels of social media engagement and lower academic performance.
