The long term potential for any of those career choices is great, and it depends entirely on you. Salaries are great, but will vary significantly based on your degree, what career you chose, and the location / company. But instead of worrying about that, see what aspects of business you're attracted.
If you're very numbers oriented you can go into finance and accounting - those jobs involve understanding a company's financial position, where the company should invest its resources (eg should the marketing team get a 10% increase or the engineering team..) etc
If you like telling stories or communicating; you can go into marketing, public-relations, or any of the communications jobs. Those careers involve coming up with a marketing strategy ("how should we convince 25-30 year olds that our power bar is the best" to coming up with a way to spreading that message, "buy $50,000 worth of ads on instagram"
If you like being orderly, diving deep into how a business functions, you can look at Operations. Operations teams solve fun/ challenging business problems. For example, Ops teams will figure out how to make factories more efficient. Tim Cook (the CEO of Apple) has a background in Business Operations, some of his responsibilities included making sure that iPhones were built to highest quality standard and on time.
Furthemore, the opportunities in Business will vary based on the industry you pick and the role you chose. Ok so what should you do, how should you pick?
- Well first focus on getting into a good college; If you are interested in an industry, try to get close to it geographically. (For example if you're interested in tech-business, go to california. If you're interested in entertainment, go to LA etc)
- When you're in college, talk to ask many people as you can - whether they're people at career fairs, your teachers, or even fellow students about to graduate. You can ask them about their career, how they got where they are, and what they're doing. Their answers will give you insights into the opportunities potentially available you.
- Based on your experience, the people you meet, hone in on what your interests are.
Hope this helps guide you and pick a path.
