Women are head of households at a rate of 40%, the statistics note that either as single parents, or making more money than husbands. Plus single women head of households or married carry the home responsibilites of cooking, cleaning, and grocery shopping.
There are government statistics IRS or otherwise that show head of household info.
So obviously, if you remove single women from this number, there are not too many household where the woman makes more than the man.
Also, not one remark about my link showing how men work way, way, WAAAAAAY more hours than women.
