Should mandatory retirement ages be abolished to let seniors keep working if they want? My 68-year-old neighbor lost his lab job last year despite being sharp, and now he's struggling to find anything because HR screens out age. Sweden abolished mandatory retirement in 2001 and their employment rate for 65-74 year olds is around 15%, double the U.S. figure. But letting people stay indefinitely might block younger workers from moving up, so maybe there's a balance between individual choice and generational fairness.
