The same critique does apply to men who use domestic help but their is perhaps more hypocrisy from those who claim to be feminists of either sex.
The same critique manifestly does not apply to men. Otherwise it would be, well, being applied.
This article assumed the feminist in question was a woman for a reason, and I'd bet my left tit is isn't because they feel only women can be feminists. There's a reason why this argument, framed in this exact way, is so well trodden. It's because we hold women to different standards than we do men. Hence the article and the thread we're having about it.
Sure, sometimes those making the argument that middle and upper class women exploit poorer women will agree, when the fact that they've let men off the hook is pointed out to them. As an afterthought. But if you were saying the exploiting is by more privileged women rather than by more privileged people in the first place, you were not applying the same critique to men.
It's an interesting point about window cleaners fascinated. I think of myself as someone who doesn't have a cleaner, but we do pay a person to clean our windows. A bloke, as it happens. The arguments about house cleaning could just as well apply to him: he doesn't have any special equipment that DH and I don't already possess or could get easily. We live in a bog standard two storey postwar terrace, so no unusual or very high windows requiring particular training or care. He's no doubt better at it than either of us would be, but I'd bet most house cleaners are better at that than I am too. We just prefer to pay him for the work rather than do it ourselves.
Yet there are no articles about window cleaners, and I bet I'm not the only person who didn't think of a window cleaner in the same way as a house cleaner. Remarkable coincidence, I'm sure, that even domestic, low rise window cleaning is a traditionally male occupation.
