Obiously, ROI will be different to each individual. For me, even a free doctorate would have 0 ROI because I can not see any benefit. My time would be better suited elsewhere. Based on that, you can imagine just how nonsensical for me to consider spending 30k+ on one To me, 30k is a down payment on a condo or 6 used cars or cosmetic dentistry or 10 times what I am spending total on my current trip to Asia or 30 times what I spent total on my trip to the Dominican Republic four years ago. Dang, if I could sell a Ph.D, I would have quite the adventurous life! Whatever you decide, I wish the best for you. It looks like you have already dropped your Ph.D. That's great news! Now you can spend all of your time here, keeping a watchful, moderating eye on The People.
