One exception can be finances. A recent report from UBS indicated that the majority of aging wives aren't involved in financial decisions, including investing.
The implications can be grim if the wife and husband divorce.
She might not be aware of what he was up to. In addition, she might be unprepared for managing her own financial future. Here are more details from Bloomberg.
The tragedy is that research documents that overall earning power tends to decline with aging. She might not have the time to "catch up."
Therefore, she could wind up with a near-poverty lifestyle not just after divorce but for the rest of her life. And that life could be a long one.
Takeaway: Wives have to pay attention to the family finances. More divorces are happening in middle age.
