The correct answer is D. Funding for Social Security
Explanation:
Social security refers to a social insurance program with benefits for retired workers and people with disabilities, in the case of retired workers this program guarantees retire workers receive benefits monthly including money and in some cases medical services. Additionally to this, social security is paid through taxes by employers and employees, which means Social security relied on the people who are still working. Considering this, when the average age of the population increases including the population of the U.S. the funding for social security becomes an important issue, because if there is a high percentage of older retired people and a low percentage of young people working then there are no enough fundings for social security, a situation that can lead to serious economic or social crises. Considering this, an issue that is important as the average age of American increases is the funding of social security as this is paid for the younger people that work.
