The U.S. Department of Labor says in 2010, for the first time since 1948, Americans 65 and older outnumbered those under the age of 20.

Chicago Kent College law professor Howard Eglit, who specializes in legal issues facing older workers, says there’s still plenty of age discrimination.

“Overall, the notion is older workers are not your best bet and that’s just wrong. It’s wrong,” Eglit said. “They bring experience, knowledge to the job that younger workers cannot bring to the job.”
