<p>Math is a legitimate major.</p>
<p>I am of the opinion that it is the person, not the major, that determines the attractiveness for employment.</p>
<p>Undergraduate education doesn’t really teach anybody enough about anything to be trained for a specific job. It’s meant to provide background and develop mental abilities. This is a good thing. Specific jobs go away, but a college education can provide you with the capacity to do many different kinds of jobs.</p>
<p>Is Math or CS or Physics or Engineering better? It depends on the person. You should go with whatever you like best. They all teach you approximately the same thing, anyway: attention to detail, an appreciation for numbers and calculation, and a logical way of thinking about how things work. The rest is details.</p>
<p>I’m a CS/Physics double major. I’m confident that I could learn 99% of math topics in a fairly short amount of time. My girlfriend is an Aerospace major; I’m sure I could learn enough about aerospace topics to be useful to a real-world project in short order. That doesn’t mean math is easy or that there isn’t a lot to know about aerospace. The majors are just close enough that a good student can pick up enough to be as good as the next guy and bluff their way through the rest.</p>
