Oh yeah there are a lot of children accepting labour conditions in the East of Asia with which we get scandalized and the. this is ok: she accepted! come on....
It must have been really hard to clean up the room and prepare three meals a day. I wonder how the women of the time did manage at all? Clearly the asian child laborers should let themselves be inspired by their example.
I don't really understand the fuss. At the time it was a normal arrangement in marriage for women to take care of the house. That arrangement in itself is not belittling to women, it is simply division of labor. Household chores are not less worthy than other labor (if you believe they are, see what feminism did, apparently it belittles women even more). The letter says nothing about his wife not being allowed to pursue other options. Even today some people voluntarily choose such arrangements. And it is merely his conditions, she is free to not accept them.
