It depends on how you look at it, working experience is never a bad direction.
Another factor that you need to think about is "who are you going to work for?" this is critical because a person with an MBA will definitely expect a higher payslip. Say you are a HR manager and there are 2 candidates for a software engineering pos in the company ya working for, both with no working experience and needs training and guidance, but obviously the expecting salary is different. In your honest opinion, who would you employ? of course there are lil factors like interviews, communication skills...etc...but i am sure you guys will likely to choose which person for the position.
Like what some had said, if your family isnt exactly waiting for you to controbute to the household expenses, why not study? the market situation isnt exactly in the best state to look for a "decent pay" job. :) for the amount of time and effort ya willing to put in that is. But, if you are gonna work for your parents, i.e self employed, best to start early. :)
p/s In big organizations, if you posses higher education level than others, well, you do however stand a better chance to get promoted provided if you are dedicated in your job. (same effort being put in by the other person with lower education level). Sad but True !
