A lot of the other ideas I recall being argued were pretty flimsy. "Women are just naturally better at service work, which is where the economy is headed", while incredibly broad, also sounds a lot like "girls are just naturally not as smart as boys and so not as good in school. We should discourage higher education for them and pigeonhole them into Home Ec". That one didn't really hold up, and the author's observation about current trends in service work isn't any better founded. Women are inherently and insurmountably better at ervice work only if you have a cartoonish view of what men are and how they interact with others.
Women performing better at service-based work actually has little/nothing to do with the personal aptitude, but rather the social trust issues between genders. Women are seen as comforting 'mothers' and men are 'villains' in western society ('bad guy', 'the Man', etc). This is why women get higher tips than men in the service industry, why a womans voice is preferred over a mans in automated systems, and so on. Until it's no longer popular to attack men in media, this will simply be the case.
I don't think the author understands the core reasons, but the reality does match.
