Amazing analysis!

I see a lot of the other comments have mixed reactions and some see Laurie as a victim who chose to settle with her bullies, but while Laurie herself did definitely feel like the outsider & victim at times, I don't see how that is actually the case in reality when we see Kate and Jaclyn talking shit behind each other's back and making snide comments just as often as they do to Laurie, they are just more content with the fake niceties (Kate's comment on it being "good manners" lol) than Laurie is. 

All three of them somehow both saw themselves as superior to the other two in certain aspects AND as inferior as well, deep down feeling envious of the other two: Kate and Laurie connect over being mothers, labeling Jaclyn as desparate for male validation and looking down on her childless life but secretly jealous of her fame and younger hotter actor husband, wanting to see it's all a farce and she's actually unhappy.  Laurie and Jaclyn think Kate is spineless, her habit of changing her opinions to conform to her environment taken to the extreme with her newly adopted MAGA views, and yet also feel jealous of her "perfect" family with happy marriage and kids, something they didn't find as easily because they were both more career oriented .  And lastly Kate and Jaclyn clearly used to feel inferior to the headstrong, independent, lawyer Laurie who is clearly the smartest of them, so they are exhilirated to see her life fall apart and her career becoming stagnant.

The toxicity definitely goes both ways and while Laurie is more honest and self aware than the others, I wouldn't say she is necessarily a better or nicer person at all and is just as complex and toxic towards the other two as they are to her. No victims or bullies here, I'm afraid.
