Final answer:
The two factors that universally interfere with family function are low income and high conflict, which impact family stability and well-being across different structures, ethnic groups, and nations.
Step-by-step explanation:
The two factors that interfere with family function across every structure, ethnic group, and nation are low income and high conflict. Low income can lead to various struggles within a household, including difficulty in providing basic needs, which can, in turn, affect children's education and future earning potential. This aspect of financial struggle often affects families for multiple generations. High conflict within a family, whether stemming from economic pressures or other sources of strain, can disrupt the stability and emotional well-being of family members and may lead to long-term negative outcomes.
Conflict theorists suggest that family is often a site of power struggles, influenced by external factors like racial and social inequalities. These pressures can create further discord within the family unit. Additionally, cultural forces, such as those prevalent in Northern Ireland, often serve as catalysts for social division that can also impact family dynamics. The interplay between government policies, economic opportunities, and individual family choices plays a role in shaping the function and well-being of families across different cultures and societies.
