Perhaps the article writer was making the assumption you imply, but there's potentially more to it than that.

Members of households all need to contribute, and while I am neither female nor married, I have heard from many married females that unemployed men do not generally tend to assume the duties of housekeeping. That is to say, the wife winds up both breadwinning and housekeeping, and the man does not contribute. This is broken.

It's sexist of me to generalize (and certainly I hope if I wind up married and unemployed, I won't let my partner take all the burden), and it may well not be what the author was thinking of, but if we take feminine anecdotes at face value there are more reasons to encourage men to be breadwinners than simply because it's their role.

Hear hear. Also, besides that, there is still a fairly widespread (if minor) stigma to making less than one's wife. It's not necessarily the writer making that judgement.

The stigma isn't that minor, among other things it is a significant cause of divorce.
