Final answer:
Married older adults are generally happier and wealthier than their single counterparts due to the benefits of stable relationships and the pooling of resources.
Step-by-step explanation:
Compared with single older adults, married older adults tend to be happier and wealthier. This finding aligns with research indicating that positive relationships, such as those found in stable marriages, contribute significantly to personal well-being. Moreover, marriage can offer financial benefits, as married couples often have dual incomes and can pool resources, leading to greater wealth accumulation over time. Additionally, societal benefits extend to married individuals, who may receive greater access to health care and other services. However, it is essential to recognize that individual experiences can vary and these general trends may not reflect every person's situation.
