Interesting proposition about having multiple post-grad degrees. I have two. One Bachelor and one Masters (by coursework), and I have job interview after job interview, and often get told that I'm over qualified, or "you'll get bored". I'm proud of my academic achievements (I completed my Masters online - wow I hear you say - but I did all myself), and the reason I am undertaking a Masters of Research this year is because I'm no longer interested in working for plebs and dumb "managers". Go to the top - get your PhD. Just do it.
