Opponents of soda taxes say they don't work. They point to a study from the University of Wisconsin at Madison. Actually, that study showed that soda taxes do work. Weak soda taxes of three percent, without any accompanying public health campaign, work weakly. But, they work. They decrease soda consumption.
In the mid-eighties the company I worked for decided they wanted to keep their employees in tip-top condition. With that in mind they built a fitness center right in our building. There were treadmills and free-weights all designed to keep us from dropping dead at our desks. The only caveat was that in order to join the fitness center you had to be fit; each employee had to pass a physical.
