If you're interested in entering that field then you should reach out to current professionals in the industry and see what it takes to get internships, co-ops, or miscellaneous jobs in their field. Reach out on Linkedin or try to find someone through a mentorship program ran by your college or something. Developing relationships and work experience are the best way to improve your earning potential.
I will note that most companies and hiring managers are extremely off-put by incoming candidates focusing solely on potential earnings as their motivator. It's unfair in many ways, I know, but you should not emphasize money as your primary motivator when pursuing any career (unless you find yourself in a Wolf of Wallstreet scenario).
