My grandfather a few years back passed a rather profound point in his life - he had been retired so long that he officially spent less of his life not working than working (despite entering the workforce at 15).
And it's not lost on me I am essentially doing double work: it's not enough for me to generate enough economic value for myself, society kind of depends on me to generate enough surplus value to cover an entire life's worth of labor (Or more! After all I started much later than my grandfather).
In a way, when Keynes predicted that everyone in the future would work a 20 hour workweek, he was right! He just didn't appreciate how much we would use those productivity gains to backfill that vacation time later in life.
If he started working at 15, doesn't that put him at 45 years in the workforce and 30 years retired? He has to make it to 105 to meet your original claim.
