Answer: c. younger workers pay taxes that cover pensions, retirement, and healthcare for elderly people.
Explanation:
The younger generation are the working age population. Because they have jobs, they can be taxed for the benefit of society. Their taxes go towards many social programs including pensions, retirement benefits and healthcare for the elderly.
If the population is aging, it means that there would be more elderly people. Elderly people no longer work and so cannot be taxed as much to provide the aforementioned benefits so an aging population presents a problem to their welfare.
