Media influence; note their concentration on millennials specifically. The media loves to obsess over the misdeeds of the terrible millennials and boomers. My personal theory to explain this is that ~everyone currently in a position of editorial power in media is gen X; note that the media never mentions gen X.

However, change is coming, as the gen Xes will start aging out soon. Within about a decade, expect the media to be decrying the villainous gen Xes and Zeds, as the top editorial jobs go millennial.
