Taxes on items such as tobacco and alcohol have been around for a long time. More recently, some governmental entities have passed legislation to tax soda and other beverages that are high in sugar. There has been talk for some time about possibly taxing foods that are high in salt, or "junk food" that is supposedly not part of a nutritionally balanced diet. Now an organization in the UK is pushing for a carbon tax on food. Citing the success of the UK's "sugar tax" in decreasing consumption of the sugar sold in soft drinks, the organization argues these "fiscal incentives" are effective in changing consumer behavior. Personally, I've never been a fan of these "sin taxes" and this article does a good job of presenting the issue from a number of different perspectives. But when does it end, and who ultimately pays?
