I went to a really prestigious high school in New York City. For the summer of my junior year, our AP Computer Science teacher hooked up a few of us with internships at the finance firms, specifically in tech (Goldman Sachs, Morgan Stanley, etc.). Now, sure, I did really well and studied really hard to get into my high school. However, I did practically nothing to earn that internship besides taking AP Computer Science. My Computer Science "expertise" was hardly valuable. I knew just about as much as any other AP CS kid in the country.
In the end, that internship did wonders for me getting into college and getting future jobs. And plus, I made 3k that summer. And yes, I finished a useful project at the firm. But the reason I had that opportunity was totally orthogonal to earning the opportunity. I know we like to boast about being a meritocracy and all that, but this is one of those cases where it was correlation, not causation.
