Barbara, a huge number of part time women workers are also on Section 8 housing, foodstamps, welfare, free medical etc. that has not been added into their yearly income.  It is not uncommon to have a woman to be receiving over $2,500 a month in these free handouts. When added in most make more than a single man does. Now the article is advocating even more freebies!
These freebie liberal programs actually discourage women from making more and becoming fully employed or they would lose the "benefits" they receive.  No where in this article is this mentioned.
