It makes more sense to say that talent is necessary but not sufficient. I'd like the writer to provide examples of people who had no apparent talent at all, even lacking whatever talents are necessary to get into a good college, and show me how many billionaires you get from that group. Saying that out of a crowd of Ivy League graduates, since only two made it big, that being an Ivy League graduate had absolutely nothing to do with it at all, makes no sense.
