<prompt> Human: Im a 23 yo without children. Ive heard that 529 plans are tax advantaged and I might do an MBA in 3-4 years. Would it be worth contributing to a 529 plan, or should I cash out a portion of my 401k if I do decide to do an MBA?  <response>: I wouldnt. The growth wont be that much and the fact that you do not know for certain that youll be attending the school means you may be subjecting some of your money to an otherwise avoidable penalty for no reason.
