I didn't get the impression from reading the article that there is disdain for housewives or stay-at-home moms. I picked up that some of these women are claiming to stay at home to raise their kids and be a housewife in lieu of work but aren't doing the work end of housewifery. I can't blame them, cooking & cleaning isn't really fun and if you have the money, by all means hire someone to do it. But to do it under the mask of being a selfless mother when some of them are clearly just lazy and don't want to report to a boss while having their own staff to do their personal work. Just stop pretending they are so selfless when they've got it all.
To me the tone of it was indicating that all women not working in careers were taking this lazy way out. It didn't bother to recognize the women that just want to be good wives and mothers.
