I don’t agree with the “follow your passion” advice, not on its face, anyway. I think that your major choice should be a combination of your own interests and skills and a pragmatic evaluation of the job market.
That said, the unemployment rate for common foreign languages (8.1%) and biology (7.8%) is about equal. I’m not sure where this idea that Spanish is a dead end but biology leads to bountiful post-college employment comes from.
Yes, the U.S. abounds with Spanish speakers…which is precisely why a Spanish degree might be useful. First of all, Spanish speakers tend to be lower-income and not necessarily qualified to do jobs for which a bachelor’s degree is required. Second of all, somebody needs to fill those positions to interact with Spanish speakers. Thirdly, there’s no need to make the assumption that a Spanish major will jump into translation or interpreter work. There’s a vast ocean of jobs that can be done by a Spanish major, not all of them directly relevant to Spanish language, even. I have two friends from college who majored in Spanish; both are gainfully employed in jobs that are relevant to Spanish, and neither works as a translator or interpreter.
On the flip side, it’s not like there are an abundance of BA-level jobs in the field of biology that can be easily had by recent graduates, either. Basically, biology and Spanish are both in the same boat as far as that goes: most of them who don’t go to graduate school will probably end up doing something that’s sort of tangentially related to their undergrad major, if at all. Biology isn’t particularly high-paying, either; recent college graduates in biology and Spanish make about the same amount ($30K), and the difference is not that large for experienced college grades (5+ years) with no graduate degree ($57K for biology; $54K for Spanish). The only place the big difference comes is for majors with graduate degrees, and I suspect that’s because biology majors are far more likely to go to medical school than Spanish majors.
All of the medical occupations that were listed could be done with either a major in Spanish or biology. In fact, one of my favorite former students who’s currently in a program to become a registered dietician was a French major in undergrad. I had some former language majors (most commonly Spanish and French) in my public health graduate program.
Nah. Money is pretty important to your happiness. It’s important not to struggle to pay the bills, and it’s important to be able to enjoy the work that you do every day. Besides, some people’s passions don’t pay: few people are ever going to get paid to read novels, go hiking, write music or attend opera concerts.

That said, you could make a middle-class income to support yourself well with either a Spanish or a biology degree; it kind of depends more on what skills you develop and experience you get.
