<p>I would suspect that most high school students really do not know that much about the subjects, "bio-" included. They have had some basic science courses but not a lot of hands-on lab work. </p>
<p>"Bio--" and now "Nano--" are hot-sounding topics. And some students believe that a degree in such a subject will get them very high-paying jobs (see posts on becoming investment bankers by getting economics degrees, becoming rich corporate lawyers, etc.). Once in college, though, exposed to more subjects, ideas, and a few courses, students can change their minds</p>
<p>Students may sound interested in "bio-" this or that, but may change their mind when they get into the nitty-gritty of the details. And some won't change their mind - or won't until they are in grad school, or even later. In my field (intellectual property/patent law) we see a fair number of people who had worked through Ph.D. and post-doc positions before they decided that research was not for them, and then went to law school.</p>
<p>Bio-- jobs are not necessarily being outsourced directly to India and China, but what has been happening is that local entrepreneurs (some US-educated, some educated in that country) have been working at building up a scientific/industrial base in those countries, and have succeeded. They are now competing in the markets with their own products (India) or with American outsource companies for outsourced lab work (China). Their people are qualified and a lot cheaper. It's frightening how quckly this is moving. Singapore and Malaysia are now looking to emulate them.</p>
<p>The other thing is that students' thinking at the beginning of college is, of course, four or more years away from the job market reality. In the past, when oil was high-priced, some students looked at petroleum engineering or chemical engineering as the ticket to prosperity. Four or five years later the job market was oversaturated with recent graduates in those fields; took another few years to even out. </p>
<p>Engineering at the college level is tougher than physical or life sciences partly because of the math and partly becasue of the heavy course load, which is designed to put a student with a bachelor's degree at work as an engineer, whereas others need at least a Master's to function as a scientist.</p>
<p>The world changes faster than we can keep track of it. Maybe the answer is in a post this morning (I think the thread was something like "college graduates have to think outside the box") with an article in which the emphasis was said to be placed less on the specific major but on the ability to do analyses and problem-solving. Who knows?</p>
