I think there are plenty of unpleasant jobs women already do. The point I would think of more women working in construction and more men working in caring jobs is that it would make the people who want to do those jobs happier.
The point of getting a broad range of people from different classes, ethnicities, gender and people with disabilities into positions of power is that the influence they have potentially has an impact on millions of people like them because they have a better understanding of those people's lives, particularly if a number of them are doing it together and not just one token individual who is expected to represent women, people with disabilities or whoever.
I would not want to go back to a time when it was difficult to see a woman doctor, or a woman solicitor and I don't think it is in my son's best interests to have only been taught by women in primary school. I don't think it makes that great a difference to decisions made about me or him if cleaners are mostly women and bin men are mostly male.
I think it matters a lot if people going around saying that men do most of the heavy work or dirty work globally, because it is untrue and believing it leads to people making poor decisions about aid, government policy and human rights for the world's poor, who are mostly (70%) female and mostly doing very heavy manual work.
Dirty work done by women, is this, for example:
'The United Nations Commission on Human Rights (UN-HRC), at a 2002 meeting of the Working Group on Contemporary Forms of Slavery, said, ?Public latrines - some with as many as 400 seats - are cleaned on a daily basis by female workers using a broom and a tin plate. The excrement is piled into baskets which are carried on the head to a location which can be up to four kilometers away from the latrine. At all times, and especially during the rainy season, the contents of the basket will drip onto a scavenger?s hair, clothes and body.?
Making up 98 percent of the majority of manual scavenging workers, these women, also known as ?Valmikis,? come from the very lowest castes in India.
?Removal of bodies and dead animals is the third most common practice of manual scavenging, preceeded by sewerage sweeping, and the carrying of night-soil by basket/bucket or on the head,?
Remembering her childhood in India at the age of seven, Chomar recounts, ?When I was a little child I would often insist on taking a broom from my mother so I could do the scavenging. The disposal of human excreta was the only thought that dominated my mind.?'
I seriously doubt that any of that leads to Indian society seeing women as equal, or that men don't do that job because of their greater strength.
