Not to be disagreeable, but to use a blanket statement and make such an overly generalized claim that social influences such as the media, parents, authority figures, and institutions of a bygone era were all positive reinforcements, is to grossly negate the struggles of all the people who were not represented by "the norm". We STILL today lack popular positive view of people who are differently-abled, for example. I could argue that many marginalized people have been engaging in what you call impression management and self-promotion in order to merely survive society. My ancestors Anglicized their surnames.

Otherwise this strikes me as a thought provoking article, but it's harder to get behind after those early statements.
