yes. life expectancy going up is a good thing - it means people can keep working even when they are older. but fewer young people is not a desirable outcome, some of the pension funds could be redirected to more benefits for child care etc.
While some can continue to work longer, most adults I’ve known simply can’t work, at least in their chosen field, much past 67. Physical pain and loss of mental acuity take their toll. Pushing the retirement age out to 70 might prevent the whole system from collapsing but we need to make sure younger people save with the understanding that working until age 70 might simply not be possible.
Living longer doesn’t necessarily mean having more productive years than in the past. We simply have the medical tools to keep people alive even if they can’t much get out of bed.
