Journalist: Many people object to mandatory retirement at age 65 as being arbitrary, arguing that people over 65 make useful contributions.
Evidence
If those who reach 65 are permitted to continue working indefinitely, we will face unacceptable outcomes.
First, young people entering the job market will not be able to obtain decent jobs in the professions for which they were trained, resulting in widespread dissatisfaction among the young.
Second, it is not fair for those who have worked 40 or more years to deprive others of opportunities.
Conclusion
Mandatory retirement should be retained.
Evaluate
The argument is prescriptive, suggesting what ought to occur. But whether something ought to occur is often contentious for people often view things quite differently. It’s important to recognize that the unacceptable outcomes are really just examples, while the key premise is the if/then relationship. The question at hand though is whether the trigger in that relationship would ever come to pass. Would someone who reached 65 years of age continue to work if permitted to do so?
