As another example, consider hard, dirty, unpleasant, even debilitating labor. In the developing world, this is often the work of women. Enjoying far less equality than in the U.S., women in these areas are at the bottom of the social ladder and get the least desirable jobs. In the poorest areas of the U.S., similar occurs. I already referenced the "resume" of Sojourner Truth, which was relatively commonplace. There is nothing biological or otherwise inherent in women that makes them unsuited, unable, or unwilling to do the heavy, dirty work of life. I'm sure they would rather be doing something different, as would most men consigned to similar work, but you do what you have to do.
