It comes down to attitude and personal responsibility for your own future. Working the drive through window at Burger King and hoping government is going to force them to give you more money (raising minimum wage) is never going to make you rich.
Getting rich starts with personal success, doing anything you do, especially classwork, the best you can do. Starting out, school is your work. How you do there will be an indicator in how you will do in a paying gig, especially when the work is hard and you are the one that must find solutions to problems.
Pick a career path you enjoy, that's key. Many careers have high paying senior positions. Prepare yourself for them, through your studies, be that in college or on your own. Make yourself indispensable at your job, be the go to guy/or gal. This will pay off eventually. If you eventually find a lack of upward mobility at your current job (stick it out for 5 or 10 years), then look elsewhere.
Your training doesn't stop after high school/college. Continually seek out skills and/or certifications that will help you and help your bosses (you need to be an asset to them).
If you have a big idea and a head for business, eventually think about striking out on your own. Note that about half small businesses go belly up because the owners didn't understand the business needs as well as they thought they did.
