What should I major in?

I have been choosing biomedical engineering but a lot of people who major in it, say it isn't great. I am looking to make some good money, enough to start my own animal rescue when I get to own my own home. I want to be able to help people as well. I chose biomedical engineering because its interesting and also helps make prosthetics and other medical aid products. Is there something similar? Is there another career where I could work in science or just help people in general or even rescue? I know I dont want to be a doctor or dentist or lawyer or anything that requires extra school. I want to earn my degree because it would get me one step above. I am just unsure since the degree is getting difficult to complete and I have felt like its my only choice for the longest. Any ideas or recommendations? I know what I want to do in life I just dont know how to get there.
