I have taken classes with students with no work experience and those with work experience.
For students with no work experience, an MBA gives you book insight, it makes things clearer, helps you learn how to put presentations together and gets you up in front of an audience. So if you go straight through you come out with advantages over a BS or BA. But someone with 5-10-15 yrs of work experience has a significant advantage over what they learn. But at the end of the day it is networking, who you know and what you seek that will make a difference in your career. You can do an MBA at Harvard and if you cannot speak with people end up unemployed or do an MBA in India, know the right people, find a great opportunity and do wonderful in your career and life.
