This is a bigger issue than simple exposure. Students studying finance/econ at Ivy League schools are on a track that starts early (our author, I assume, applied directly to Penn's Wharton School). The expectations and goals start in high school then, sometimes earlier. It's hard to get away from those expectations and pressure, and students emerge at the end of the conveyor belt onto Wall Street before they even know it, ready to earn their "seven in seven" (a milly in seven years).

I think the bigger deal here is talking about start-ups as a viable career option all around (cultural shfit?), and encourage kids (high school and college) to experiment while in school, since risk is relatively low and time is readily available for most. A better system of on campus incubator/meet-up programs would be a nice complement, too.
