Tyler Cowen did an 'ask me anything' at Jane Street when I interned in 2016. One of the interns asked him exactly this: "What do you think of the fact that we all work here instead of, I don't know, curing cancer?"
He replied with, roughly, "Those of you who work here probably couldn't do anything else other than perhaps math research. Arguably, working here is the economically efficient use of your time."
I think about whenever I see a comment like this. Quant firms select for a very specific set of skills. In particular, I've found that many traders/software engineers in quant are very smart but not very self-directed. Places like Jane Street work well for people who can excel, but only when given a lot of structure and direction. I think this is not unrelated to why so many people 'accidentally' end up as traders after going to an Ivy League school!
