Little Em'ly's desire to be a lady leaves her vulnerable to seduction by the upper-class Steerforth: for a woman (and especially a working-class woman) there were few avenues for social advancement outside of relationships with wealthy or powerful men. Emily's ambition also marks her as suspect in a society where women were meant to be selfless, although her desire to help her family tempers this slightly. Regardless, seems to drive Emily is a need to escape the precariousness of working-class existence, as symbolized by the sea. Ultimately, however, she only succeeds in trading the uncertainties of working-class life for the uncertainties of life as a mistress, and this passage foreshadows the self-destructiveness of her actions with the image of her running out along the unstable jetty.
