If Buffett and Munger wanted,they could certainly point out that Coca-Cola and Pepsi both benefit from being on EBT/SNAP lists as acceptable foods to purchase, and ask that soft drinks as a class of foods be removed.

Last I looked, about 9.5% of total EBT/SNAP money for food (that is, money from taxpayers that are supposed to help feed those in need properly) is spent on soft drinks. No person in need, needs soft drinks, especially when we have high rates of diabetes and obesity among the poor.
