Fun experiment: Keep track of how many Hulu commercials feature white alpha males.
Almost none, with the exception of Deluth Trading Company. Even the Home Depot casts a flannel-wearing manly black guy loading mulch into his Ford pickup, while the weasely white beta is led around by store by his wife.
Most companies seem to hate white alphas, if not our money.
I'm no advertising expert, but I suspect these companies have done extensive tests and determined that white males (especially older ones) and Asian men are almost immune to TV advertising influence. I can't think of a single product I've ever purchased after seeing an ad for it on television.
Conversely, it's pretty much understood that most U.S. television content is aimed at women and blacks. That's why you see the trends you've identified in TV ads.
If you have to say you’re an alpha, are you really an alpha?
