I'm not buying a lot of this "motif" usage stuff, but if you want to speak entirely speculatively, I'll bite.
Marxism extensively argues that it is easiest to oppress people when you categorize them differently. An example would be how poor whites weakened the rights of free slaves in post Civil War America. Marx would argue the rich propagated racist beliefs to the poor whites who then limited the rights of other poor people. The end result is the poor limit their own democratic representation. Scientific Socialism is an essay by Engles (coauthor of the Commumist Manifesto) where he argues all oppression is based off of sexism (infantilization, dehumanization, objectification) and shows how the concepts of oppression are modified for race and class, so each group appears different but are actually the same. How this would apply to advertisers might be to preserve the status quo, or to make people feel bad to compulsively buy.
Not saying I agree with every aspect of those arguments, but it is a well documented attempt at answering your question.
