Getting a degree in a well-respected discipline (mechanical engineering, in my case) also opens up a lot of jobs (cost analyst) that aren't necessarily related to your major but have similar required skills (analytical skills).
This is more of a beat than a brag since I failed to find a mechanical engineering position that worked out and went with whatever was available
but I am in a muuuuuch better position than most of my friends that majored in easy disciplines.
Based on my experience I think if you haven't figured out exactly what you want to do out of college then studying something like engineering is probably a good idea; yea it blows when your friends are at the bars on a tuesday night and you're stuck doing work but it is worth it when you're looking for a job.
However, that advice is more tailored to someone coming out of high school. If you're in your 20s and are thinking about going back to college I think you should have a pretty decent idea of what you want to do post-college and you should tailor your education to that, obv. And do extracurriculars and internships and ****, that helps too (lack of experience was my downfall).
