(On the upside, the men's fashion industry might get a big boost from this revolution -- imagine if you could market something besides the exact same tuxedo for every man going to a formal event. Imagine if a man's tuxedo could go out of fashion as quickly as a woman's evening gown. Cha-ching! Twice as much money for the fashion industry generated by every Oscars night. Think outside the box, people!)
But, if we really are naturally and contentedly simple-minded apes, then it’s a waste of energy to remind us to behave like that, because we would already be doing it. If we are already the kinds of men portrayed in beer commercials, then the beer commercials don’t need to tell us how to behave like that.
