It doesn't seem unlikely to me at all. Lots of people are smart or successful despite coming from a broken home. Weird example but Eminem was extremely poor growing up.

You're misinterpreting. When sorted by annual income, the top 5 incomes all have the same value: 380,288. This points to something weird going on in the data, unless all of those specific participants happen to work the same job at the same company. Even then, years of experience and salary increases would likely differ.

Perhaps that value is an integer representation of a categorical value, like wealth percentile or tax bracket?

Oh this is a fascinating coincidence- 380,288 just so happens to be the income reported by Vice President Harris and her husband on their 2021 federal tax return.

I have 7/10 ACE's and am a self-taught senior software engineer. We exist. Not always well, and good lord is it hard to find empathy from coworkers who had the "standard" life advancement, but we exist. Among folks who've gone through the same stuff as me, they are not doing nearly as well as a group compared to others in my generation.

(But yeah there's some data checking that needs to be done as denoted elsewhere in the thread)
