Shiv, Caroline, and strivers
On a rewatch I just noticed that Caroline (old money) consciously chooses to “marry down” class-wise, as does Shiv. Both of them end the show partnered with strivers.
Caroline delights in making fun of Peter’s tacky class aspirations. Before that she was with Rory who iirc seemed to be kind of a barnacle. And, before that, she married Logan, who was new money.
Shiv married Tom, a man “fathoms beneath her,” whom she later calls “striving and parochial. Striving and parochial is Peter Munion to a tee.
Shiv married Tom after a period of life where she was “all a mess,” her self-esteem lowered so that she married down to protect herself. Caroline seemed to move down each relationship, going from powerful, rich, new money Logan to Peter, as presumably her self-esteem took hits from Logan’s infidelity and her children choosing him over her (allegedly).
I find it interesting how Shiv’s choice of Tom seems to echo her mother’s choices of partner.
