Both the second and the third link paint a much more balanced picture than I think you imply. They both make the important point that there is no F to M wealth gap resentment in partnerships where the man takes on additional domestic responsibilities that are traditionally reserved for women. That makes intuitive sense both practically (bandwidth) and symbolically (fairness/partnership). The HBR/Herald thing goes into detail. And the US News article points out the status quo has already grown to 20% female breadwinner households. If it wasn't a successful model, it probably wouldn't be growing in share.
