Final answer:
The growing number of people in the workforce and the increase in the number of elderly individuals are straining the social security systems of Japan and other industrialized nations.
Step-by-step explanation:
The growing number of people in the workforce, along with the increase in the number of elderly individuals, is straining the social security systems of Japan and other industrialized nations. As more baby boomers reach retirement age and start collecting Social Security, pensions, and Medicare, there will be a larger number of people who are no longer working but are relying on these benefits. This creates a heavy burden on the smaller, younger workforce. The dependency ratio, which is the ratio of children and elderly to working-age individuals, will be affected by this change.
