The idea of taxing soda to trim waistlines has shown to be an ineffective way to reduce obesity. I agree that people who love soda will probably continue to buy soda. Several studies have shown this. According to the Centers for Disease Control and Prevention, states where soda taxes have been implemented have the highest obesity rates.
And, an article published in January 2010 in the journal Contemporary Economic Policy finds that while an increase in soft drink taxes would raise revenue for governments, it would likely place an unequal burden on those with lower incomes.
