I am one of those oppressed ultra-orthodox women (to be fair I only really feel oppressed at Passover!) and I tried watching this show, both seasons, but couldn't get past one or two episodes. Not a big fan of reality tv in general. All I can say is I would a million times rather be ultra-orthodox than have a mother like Julia. It borderline child abuse what she does to Aaron. And I would NOT want to discuss my sex life with my mum! Ever. However rich she was.
Orthodox Jews cover a huge spectrum of observance. Julia is from the Yeshivish community - called so because they value yeshiva/torah study. In that community many men will stay in yeshiva for years after marriage while their wife works. (akthough many men go to college and get jobs also) As a result Beis Yaakov type schools give the girls excellent educations so they can get high paying jobs and become computer programmers, work in business, therapists, etc. and support their families if they want to marry a long term learner. There are very few jobs a frum girl can't do - but most girls would not choose a career in something that impedes family life. Movie acting or theatre can be difficult due to shabbat observance and tzniut (modesty) restrictions.
The Yeshivish community itself has a wide spectrum. You can be an instagram influencer and go to broadway shows. Or be a school teacher married to a kosher slaughterer and not allow secular books in your house.
And if being really restricted is too difficult for you? Its generally acceptable to move to a different group, which can be as simple as moving schools.
Not all religious men are patriarchal controlling bastards, although sadly there are some. Many are wonderful, some are mediocre. And if someones spouse chooses to be less religious - in some communities, mostly Hasidic ones, this can be a real issue where the non religious parent loses custody. WIth some couples they even stay married, while respecting each others lifestyle choices. WIth others they have amicable divorces. (which Julia and her poor ex seem to have, although I do wonder if it is tru about the get refusal)
I am not yeshivish, I am chabad but in my family we have academics, doctors, therapists, influencers and a whole bunch of Rabbis. And a wide wide range of observance and how much we let secular culture into our lives.
