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.
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.
