Though there's a proposal to accept elder age for employment, why the majority firms still count their age?

Question

Since the count on population are descending,so elderly folks are the treasure roles for employment, then why the majority companies are still counting their age?

Answer 1

Employers are skeptical about hiring the elderly - those over 55 - because they have concerns about health problems (higher medical insurance costs), productivity and efficiency, and may require more time off than younger employee. Such misconceptions are widespread, even though most of the "senior citizens" have a better work ethic, more business experience and exposure to problems (as well as solutions), will be loyal, (not leave the company at the first opportunity) and in some cases, are in better health than younger co-workers.
