Two working couples:
- Two incomes
- Shared health plan (more expensive but less than 2x single?)
- Shared apartment (more expensive to support two occupants but less than 2x single?)
- Opportunities to reduce duplicated expenses when possible: e.g. single set of furniture, single car, joint loans (e.g. mortgage + closing costs), repairs, etc.
If one of the partners is not working I believe there are still advantages but they might be harder to quantify. Even if it means cutting out one of the incomes, having a time-available partner can be advantageous in other ways. Time to cook vs. eat out (more cost effective), organize bills, find discounts and deals (e.g. credit card churning for saving ~1k-2k a year on flights), organizing activities to maintain health, arrange doctor visits for preventative care, etc.
Obviously, this equation changes when one is a dependent but if both are independent and work together I feel that the math would favor couples.

- double income
- motivation and accountability
- kids
- delegation of responsibilities. You don't have to do everything yourself.
The current divorce rate for first marriages where both partners have a bachelors is around 10%.
The thing I don’t think these statistics always reflect is the societal changes over the decades. Why people marry, when they marry, ease of divorce, the effects of widespread divorce on upcoming generations, it’s all changed enormously over time.
financial health is not a goal, but a means to an end.
Getting good financial health is a means to having kids (ie, you will give your kids the best advantage they could if you're more financially capable).
Every case is different, but I don’t think you have to be under one roof to significantly help some people keep their independence and avoid spending money on caregivers that are very expensive especially
On the other hand this advice is 50% right if you ever do get a divorce. Those things are so expensive and leave a huge hole behind. If you were the primary money earner you are likely to pay for years.
