Like most problems, it won't be addressed until someone finds a way to make a bigger profit off pushing for health instead of rewarding and encouraging ill health. The food, medical, pharmaceutical, and insurance rackets are simply making too much bank off of the ever-expanding masses. The parallel with "drug war" profiteering is obvious. As long as most of the chubs are able to live long enough to reproduce and work a cash register for 20 or so years then conveniently drop dead between 40 and 50, everything will remain as it is.
