In reply to John2:
Your points are valid, but there is an earlier backstory which we are not shown and which I suppose I am guilty of imagining for myself.
We only really know about her life AFTER meeting Hal. Up till then she was a promising "golden girl" student looking toward a future in anthropology.
In the earlier flashbacks she seemed to me to either have no knowledge of her husband's dealings, or to be coping with them via plausible self-denial.
In the present day, she does in fact make a genuine effort to "start at the bottom" - although reluctant, she does in fact take the receptionist job, and seems to grow into it after an incompetent start. She is trying her best to better herself. Sadly, "her best" isn't quite good enough...and yes she lies to the Peter Sarsgaard character (but his own flaws run VERY deep anyway...)
I suppose that when I say I began to feel sympathy for her, I mean "relative to the other characters who seem at first to be painted as so much better, morally, than she is, but who as the film goes on, reveal themselves to have some rather negative character aspects"
In short, Woody is saying that everyone is rotten so why should we only pick on the most obviously rotten ones
Even the son was a bit of a prick - the scene where he is sucking up to Jasmine and Hal about how Hal's visit to his uni enabled him to suck up to everyone at uni. I thought he needed a slap right then and there
