Except that he later goes on to describe how this is also affecting women more and that we should be paying attention to that as well? I don't think anything the author said is actually disparaging of women, in fact there was quite a bit of the opposite, talking about how vital their role in society has been. He's not blaming working moms, he's using them as the perfect example that a person can leave the workforce for years at a time and rejoin without much loss.
Where is he blaming mothers for this situation in the statement you quoted?
