I dunno. I think that keeping retirement ages where they are now and having the aging population/increasingly life expectancy eat into the workforce is fine thanks to automation. Automation and the increases in productivity it brings could allow us to keep our economy running just fine even as the workforce participate rate declines. Moreover, it might be key to preventing the social unrest that automation may bring... if automation eliminates a third of all jobs, the aging population and increasing life expectancy could eliminate a third of the workforce, and the two cancel each other out and working age people can still work.
