[badpun]

The Japanese have been supposedly working on robots to support their aging population for a couple of decades now. It sure seems to be extremely difficult to make progress in this field (and in robotics in general).

Also, as you noted, half the picture are people whose problems are self-inflicted, mostly due to bad lifestyles. Right now, companies profit off bad lifestyles (first by selling them and them by helping to manage consequences). No comercial entity will profit from population keeping itself healthy and balanced, as mostly involves substraction (NOT doing some things) and not addition (doing/buying). It's a awareness and policy issue, and can only be fixed through either campaigns promoting good living, and through policies which enable it (more vacation time for workers, healthier food in stores, less stress due to economic pressures etc.).
