First, not sure how bringing up a long dead, fat, alcoholic and over zealous cold warrior from the 50's has to do with the obesity problem.
Second, most investors aren't evil, they are self interested. One might even argue they are the most responsible members of society, they are saving for their futures, both as individuals and pension funds, while at the same time financing the possibility economic growth and employment for others.
Thirdly, much of the "fast food" obesity problem is an effect of both parents working in the modern economy. It has always amazed me how much "fast food" my sisters' kids eat, both parents work. All my sisters cook very well, but who has time. Compare that to our childhood, mom was home, we took our lunches to school, dinner was at 6:00PM every night, you could set your watch by it. Guess my sisters could cook healthy meals and send their kids to bed at ten o'clock five minute after they've eaten.

Lastly, we know obesity when we see it, but the statistics are skewed. Take the Body Mass Index, both athletes and the obese show up obese. Everyone old enough to remember the President's Council on Fitness from school, I think JFK started it, everyone in gym class was obese according to BMI.
I'm with Soren on this, why add one more penalty on folks already struggling. Besides we already screwed the poor by destroying affordable use cars with "cash for clunkers".
