Chart 1 doesn't make sense to me. It seems everything else is about the median YEARLY earnings, and the word lifetime in the context of this doesn't make sense.

Chart 1 doesn't make sense to me. It seems everything else is about the median YEARLY earnings, and the word lifetime in the context of this doesn't make sense. Maybe it means the median yearly wage for each individual? Like if I worked exactly 3 years in my entire life and I made 25k at 25, 40k at 40, 60k at 60, my median earnings would be 40k. That's the only way I can make sense of that.
