<p>"… but why do all these science and engineering students go? "</p>
<p>Not an investment bank, but when I worked at a commodities firm we had a whole quant department staffed wth ex-physicists and bailed-out physics doctoral students. They left their field because they were downsized from their area of training and could not get work in their field, saw that the students ahead of them could not get tenure track positions, etc. Others were there because they just got interested in the markets; that’s how I got into it.</p>
<p>My nephew started out intending to be a chemical engineer, but proceeded to pull C’s in his intro Chem E courses. Many at his college were heading to finance, so he checked it out, took some courses, and got a relevant internship. He found he was better suited, by intellect and personality, to go that route. </p>
<p>Others are no doubt attracted to compensation prospects. So there are a variety of factors at play. However, in any event, the preponderance do not go . Only a few schools get highly recruited for these elite high-paying jobs. Even at the few schools where as many as 30-40% are doing these other things, that means 60-70% aren’t. And there are very few engineering schools whose students are that attractive to investment banks.</p>
<p>"…spend 4 years mastering subjects like engineering and science and then do nothing with what you learned "</p>
<p>In my nephew’s case, once he found he was not the ace engineer he had intended to be, he switched fields, and courses, accordingly so there was not so much class time that was wasted. There are majors in engineering that are really more “applied mathematics” in nature, and some programs actually have applications to financial markets directly.</p>
<p>But you’d be surprised how quantitatively complex work related to financial and commodities markets can be. All their training is not wasted. These physicists were hired because those were the people with the quantitative skills and mathematical training to do the work. The only time I used calculus in the workplace was while working in finance and commodities, not when I was an engineer.</p>
<p>What is wasted is the content-specific coursework. People who have gone through a whole technical engineering major will take a bunch of content-specific courses that they will never use if they go the finance route instead. I think that’s a sub-optimal use of their one shot at a college education, and a shame for them personally. But I don’t think they are slighting mankind or anything, just themselves.</p>
<p>We live in an integrated market economy. We need people who design stuff, and we need people who help finance stuff and generate $$ so those people who design stuff can become employed. We need good and motivated people in every stage of the effort.
The overall effort is most enhanced when at each link in the chain people are doing what they are individually best suited for, and are most motivated to do.</p>
<p>Those people are getting hired by the banks because they are best suited to do the needed work, by intellect and training. Even if specific science is not drawn upon (though the math aspects may well be).</p>
