The percentages for each group seem to include everyone in the higher groups as well.
I'm making this assumption based on the percentages of the 60-year old graph: 76.8%, 50.9%, 32.2%, 20.6%
I guess I was thinking about this plot like a histogram which makes more sense in a bar chart like this. Read like that, the percentages in each bucket are: 25.9%, 18.7%, 11.6%, 20.6% for the age 60 chart and 17.7%, 7.4%, 2.1%, 2% in each range for age 30
I think the data's being presented in a strange way.
Since it's "people who make over $100k at least one year of their life", it makes sense that older people would have higher numbers.
They've been working more years, and because of that they usually have higher paying jobs due to having more experience or moving up to management positions.
