Emma Green has an interesting analysis in The Atlantic on why marriage is viewed very differently by richer and poorer women and societies. Here's an excerpt.
Taking a stand against patriarchy is much easier if you're well-educated, have a stable income, and live in a community where you could theoretically find an educated, employed man to marry. For poor, uneducated women, especially those who have kids, the question of whether to get married looks a lot different: It's the choice between raising children on one or two incomes, between having someone to help with household chores and child-rearing alone while working multiple jobs.
And that's the big difference: For a poor woman, deciding whether to get married or not will be a big part of shaping her economic future. For a wealthier woman, deciding whether to get married is a choice about independence, lifestyle, and, at times, "fighting the patriarchy." There's a cognitive dissonance in Ehrenreich's straight-up dismissal of the economic benefits of marriage, because the statistics tell an awkward truth: Financially, married women tend to fare much better than unmarried women.
This topic has been covered extensively in The Atlantic and other publications. But the way this question is covered in the media tells a similar story of the fundamental divide in who can afford to stand against marriage on principle. Take, for example, two articles on marriage in the New York Times: One is about a 35-year-old Argentinian woman who fears that marriage will erode her independence, while the other is about the vast economic disadvantages that poor, single mothers face. The women profiled in the second story aren't worried about being controlled by men or losing their carefree lifestyle; they're worried about how one income can feed, house, and clothe two (or more) people. Wanting a certain lifestyle, or even wanting to fight against societal pressures to marry, are both questions of privilege.
