My wife got a Bachelor's from UCLA, then a Master's in Museum Studies from University College, London. She then worked for free (it was called "interning" - which is kind of crazy for someone with a master's) at the San Diego Air and Space Museum (some kinda weird folks there...), and the USS Midway. She gave up weekends and time she could have spent earning an income. It amounted to nothing, though she did get a neat volunteer dinner from the Air and Space Museum. Now she has a normal job in a normal office because she has to pay off the debts from school and can't afford to work for free.
Anyway, your anecdote is valid, but so is mine.
