Good point. I mean “typical” as in, entirely expected within a nontrivial portion of the population. Where absolutely nobody would be surprised that you’re making this much.
Is it typical for the general population to make a million a year? No, but it is entirely typical for investment bankers and quants at hedge funds. To say that is atypical of the average worker in America — well, of course, but that isn’t a very meaningful statement when you’re specifically discussing people in investment firms. And that’s what this article is about — the subset of the population for which this is entirely normal and expected.
Since when does "typical" mean "graduated from a top 10 school"? That's why you're being downvoted.
