- What hardship / not-boring is (i.e. Buffet's father became a congressman when he was still in his formative years; but that doesn't count for Bezos because his adoptive father was well-off).
- What proportion of "old" billionaires come from it
- What proportion of "new" billionaires come from it
- The difference between the two proportions, and whether it is significant. A brief mention is made of inherited wealth (which is arguably the most boring, by the author's definition) but isn't discussed further.
- Why billionaires are used as the definition, given that exclusively analyzing outliers is probably a poor way to assess class mobility.
The article optimizes for words rather than clarity of thought.
