Dear Evie:
What an interesting thread: you brought up an issue and resolved it, all in your original post. I have nothing to add. Except maybe this:
You wrote, “every nasty, venal, aggressive and narcissistic person I’ve ever known or known of suddenly seems to having their day in the sun.” You have an example of a woman who advances her career acting in such nasty, venal, aggressive ways.
In my experience, a lot of aggressive, abusive people do not get their day in the sun and do not benefit financially from their behavior. Only a minority of them do. Most lead dysfunctional lives, not benefiting from their behavior outside temporary emotional relief and feel-good moments.
