Get some work experience. You're better off working at a Big 4 than going straight into an MBA program, because if all you have to offer are credentials (degrees, accreditations, etc.) you're not going to be any more employable than someone with just a college degree - in other words, you'll be up for the same kinds of entry level jobs as some college grad with zero experience. Also, you want to establish yourself NOW as someone who can handle it in the real world, rather than get into the dangerous trap of becoming a degree/credential collector.
Again, all the degrees in the world are no substitute for experience. It may be harder for you to see that now since you've been in school all your life, but believe me even if you work for a few years in so-called "slave labor" (as you put it) in the real world, you will lay a much better foundation for your professional career.
