Unfortunately, the Sciences don’t pay very well.
It would be interesting to know what percentage of science majors or phds in science, work in there chosen profession.
I guess the question then would be do you care THAT much about money or do you want to help further humanity's knowledge? Plus private R&D can pay quite nicely, people only seem to consider University research as "science work" when that is absolutely not the case, its just the worst compensated science work. (which is another problem, because for the information we get it SHOULD be well compensated)
