Final answer:
The percentage of men aged 65+ in the workforce today is higher compared to 1900, due to improved health and changes in retirement norms and systems.
Step-by-step explanation:
The percentage of men age 65 and older who are remaining in the workforce today has increased compared to 1900. This change can be attributed to a variety of factors, including improved health and longevity, changes to retirement plans and social security, and a shift in the perception of retirement. Despite the influx of women into the workforce and the lack of long-term upward or downward trends in unemployment rates, older men are indeed participating in the labor force at higher rates than they did in the past.
