In order to do many jobs, your employer will only want to know that you have a degree, and what it is in, may not matter. The purpose of a college education is not to get training for a job, but to learn how to learn, no matter the degree.
If you're just interested in a job, a technical training school might be better than college.
Useless degrees? No such thing. Degree that will get you the most money? Engineering. Degree that will get you the least money? Education.
