Fat Tax
More and more countries are adopting fat taxes (adding more tax to junk food and soft drinks) in an effort to curb rising obesity rates and also to offset the economic costs of obesity. Numerous studies suggest that as the price of a food decreases, individuals get fatter. Yet, since the poor spend a greater portion of their income on food, such a tax has been said to be regressive. In your thesis, take a position for or against the fat tax.
