Upfront, so you know my "politics," I am a 40ish working mom with an advanced degree, and 2 toddlers at home. My husband and I make about same salary, and financially either one of us could choose to stay at home.
Overall, I found Ms. Hirshman's manifesto to be overly harsh and unbalanced. I do agree with some of her points -- women should be able to be financially independent, and it is important to get an education and pursue something you enjoy, and I also agree that changing diapers and some other "baby duties" can be a bit tedious (although for me personally, those things are far eclipsed by the joy I get from my children). I also agree that husbands need to pitch in, and do an equal share around the house and with the children. I also think that female attrition in the workplace does make it more difficult to get equal treatment.
However, that said, I miss my children terribly and I can certainly understand why a parent would want to be home with their kids or work part-time. Furthermore, I think it is absolutely ludicrous to expect a parent to sacrifice the happiness of their family "for the good of womanhood/society." It seems that searching for a way to align family and societal interests would be more productive.
I do think it is risky to quit working and be completely dependent on your spouse for income. Although my spouse and I trust each other completely, I have seen men take advantage when the balance of power (money) shifts in their favor -- so, I understand the concern. In my experience, the workplace seems to be accomodating to me as a parent, but less so for him (i.e. my employer tolerates my taking time-off for kid-related things much better than his). In other words, our culture/society needs to change so that it is not so lopsided in how it treats/accomodates moms and dads -- which is also part of her mantra, but does not get the attention it deserves.
As a mom, I have noticed that early-on alot more of the child-related burden is on the female; no matter how supportive a husband is, he cannot be pregnant or nurse the baby. Also, I have noticed that even though my husband is an equally involved parent, my children tend to prefer mom over dad (I suspect this will change over time as they grow up). In summary, her Manifesto totally ignores the fact that early motherhood is exhausting for the female esp. when working, and that work often becomes alot less interesting/meaningful when you become a new parent.
I really respect women who stay home -- it is a difficult job and requires unending patience and love. I have a hard time criticizing someone who chooses that.
I do not think the answer is to flog and insult women (or men) who choose to stay at home with their children. I think the answer lies in understanding, accomodating, education and tolerance.
I would like to see society/employers allow parents some flexibility to place greater emphasis on their families. I would like us to learn as a society that spouses should treat each other with respect and as equals, no matter what the role. I would like parents to raise their male and female children to expect to "share the load" whether it be household responsibilities or income. In short, I believe, while Ms. Hirshman's book contains some basic truths, it does not offer a palatable solution, and is often critical and judgemental.
