One of the flaws in trying to use the tax law to influence behavior is that legislators too often target symptoms rather than problems. That’s not the case with all taxes. For example, a tax designed to defray the cost of trash removal that is based on the cost of removing each pound of refuse focuses on the problem, namely, the burden to a government of removing the trash. The fact that the tax also serves as an incentive to reduce trash by recycling and cutting back on purchases of throw-away items is a welcome side effect. On the other hand, proposals to tax soda and “sugary beverages” not only attack a symptom rather than a problem, but also discriminate in favor of other items that produce the same symptoms as those generated by the drinking of soda and sugary beverages.
My opposition to a tax focused solely on soda has been explained in a series of posts, starting with
What Sort of Tax?, and continuing in
The Return of the Soda Tax Proposal,
Tax As a Hate Crime?,
Yes for The Proposed User Fee, No for the Proposed Tax, and
Philadelphia Soda Tax Proposal Shelved, But Will It Return?. On March 24, 2010, my editorial, Why Phila. Soda Tax Already Has Gone Flat, was published in the Philadelphia Inquirer.
Last week, in his
Opinionator column, Mark Bittman, writing about efforts to make wholesome foods more available to residents of inner city neighborhoods, lambasted opposition to soda taxes. He rued the failure of proposals in New York, San Francisco, and Philadelphia, which he attributed to “heavy campaigning by the beverage industry.” He claimed that any mention of a soda tax brings “hysteria from people (only some of whom are industrial-food shills) who claim that a soda tax is tantamount to a government takeover not only of food manufacturing but of our lives.” He noted that “Even more incredible, there are people who believe a soda tax – admittedly regressive – is somehow an attack on the poor.” He argued that a soda tax would reduce soda consumption, and also would reduce obesity. In his words, enactment of a soda tax would encourage politicians “to tax other disease-causing ‘foods.’”
Soda consumption, or more accurately, excess soda consumption is a symptom of a problem that reaches beyond soda. Too many Americans have poor eating habits. When combined with another problem, insufficient exercise, consequences such as obesity, heart attacks, strokes, and a variety of other health issues that, no pun intended, tax the health care system and require increases in government and private sector spending on curative, rather than preventive, health care, are pretty much unavoidable. Taxing soda does not solve the problem, nor does it do much to alleviate the symptom. It is unlikely that a soda tax would reduce soda consumption by a sufficiently significant amount to make any sort of meaningful dent in a culture of poor eating that extends way beyond inner city neighborhoods. Even if a soda tax causes people to purchase less soda, perhaps to the point of purchasing so little soda that the tax raises little or no revenue, people will spend their “beverage dollars” on things like diet soda, fruit juices, coffee, tea, and other liquids. Recent studies show that diet soda, especially when consumed in large quantities, poses health risks. Fruit juices contain fructose, even if unadulterated by the addition of corn syrup or cane sugar. Coffee and tea contain caffeine, which is harmful to some individuals and also poses health risks. Oddly, the sugar tax proposals that have been floated do not reach the cup of coffee or tea to which sugar has been added, in some instances to the point of making soda seem bitter.
However much of a risk soda poses to a person’s health, it is far from the most unhealthy substance people ingest. Consider, for example, donuts. Donuts not only contain sugar, they also contain fats that pose no less a risk to a person’s health. Why are there no proposals for donut taxes? Consider, as another example, cakes, pies, and other pastries. These are yet more items that combine sugar with fats, providing a double dose of health risk. Perhaps a pie tax or pastry tax has been proposed somewhere, but I’ve seen no push for a cake tax or pie tax along the lines of the effort to enact a soda tax. Why?
The comments to Bittman’s column are informative and interesting. There seems to be a disagreement on whether the tax on “sugar-sweetened beverages” would include a tax on beverages containing high fructose corn syrup. Even if a proposed tax reaches drinks containing either substance, why give tax-free treatment to other food items that contain high fructose corn syrup? One comment noted that “almost any ‘food’ can cause disease or other problems if consumed to excess.” This is quite true. Even excessive consumption of water can kill a person. This comment also questioned why a government should be “meddling by way of legislation in people’s dietary affairs.” As one who has argued against using tax law to accomplish social goals, I must agree that there are serious disadvantages to trying tax law solutions to a problem, made worse by targeting symptoms of that problem. The problem isn’t the food item. There are people who drink soda and eat donuts and pies, and yet are in fine health. There are people who have serious health problems caused by bad eating habits and lack of exercise who don’t drink soda. As another comment noted, “More kids are fat today because they don't get any exercise. If you want to ‘do’ something about it, you should be supporting sports programs or a mandatory one hour a day of PE at the schools.” Yet some politicians are making careers out of chopping school budgets and axing sports programs.
In a rebuttal to Bittman’s claim that soda taxes are an attack on the poor, another comment argued that the soda tax “is an attack on the poor” and that “We have too many regressive policies and we keep adding to them as we refuse to tax income, capital gains, etc.” The person making this comment then asked, “Why do we use ‘sticks’ on poorer/middle class people to get them to act correctly, but have to provide ‘carrots’ to the well-to-do?” Good question.
Yet another comment noted that, “If you're part of the Tea Party and you don't believe government has any role trying to improve the health of the American people, that position is certainly easy to understand but it is wrong. The U.S. (New York, actually) pioneered public health over 100 years ago, and trying to prevent obesity and diabetes should be no different than preventing cholera and dysentary [sic] were at the dawn of the public health movement. I'm sure in the 1880s there were those who maintained the government had no role trying to interfere with the free market in contaminated drinking water. Fortunately those people did not prevail.”
The question isn’t whether governments should be concerned with citizen health. Clearly they need to be. For example, when it is time to raise an army in defense, governments need healthy individuals. The existence of too many unhealthy individuals will break the backs of health-care systems, whether funded by government, the private sector, or some combination. The question is how does a government ensure that its citizens are healthy.
A tax designed to ensure a healthy citizenry needs to be focused on the burden imposed on society by a person’s failure to maintain a healthy lifestyle. How that can be measured is problematic. Perhaps it is easier to tax unhealthy foods than to figure out the computation base of a user fee designed to relieve society of the cost of a person’s bad habits, much as it is easier to tax cigarettes than it is to impose a user fee on individuals who develop illnesses on account of smoking. If the approach that is adopted is to tax unhealthy foods, then the tax should be on all unhealthy foods, not just soda. Yet, the problem isn’t the food, other than foods containing poisonous substances; the problem is excess consumption. Yet a tax on large restaurant servings would be flawed because some people make two or three meals of their purchase by using the badly-named “doggie bag.” Similarly, a tax on large hamburgers could easily be circumvented by purchasing two small hamburgers. Ultimately, the practical and administrable solution is to limit taxation to those substances, such as nicotine, that pose a high risk of harming health, and on items that contain such substances.
Another comment suggested the opposite of taxation, namely, incentives to “those who achieve desired BMI numbers.” This is a thought-provoking idea. Would it work? Perhaps. Is it administrable? Maybe. Ought it be government regulated? Probably not. Some health insurance companies already provide similar incentives, namely, premium discounts to customers who work out at a gym more than a certain number of times a month. Though there is a good argument that private sector health insurance companies have their own incentives for doing this, as it is cheaper to reduce premiums than it is to pay out larger medical expense reimbursements in the future, the current condition of American health and the proliferation of obesity cause me to wonder why the private sector hasn’t made any significant progress in this regard.
Yet another comment made an excellent point. The federal government “is actually subsidizing corn, and hence [high fructose corn syrup], and beef, and other food animals that are fed corn.” Thus, as the comment points out, “government interference [in what we eat] is already here, unfortunately in such as [sic] way as to decrease the price of unhealthy foods and maximize consumers’ ability to buy them.” Are the advocates of government subsidies for specific agricultural businesses among those who are lobbying for a soda tax? I doubt it. Are the advocates of government subsidies for specific agricultural businesses among those who decry government interference in private life? I would not be surprised if the answer is yes.
It is not surprising that government taxation and spending polices, as a whole, including user fees, tax credits, and rebates, work at cross purposes. Designing tax policies that are coherent requires much more care and attention than slapping a tax on one symptom of a much larger and more pervasive problem. The prediction that a tax on soda will lead to taxes on other items is no guarantee that a tax on soda will be followed by a tax on donuts, pies, or hamburgers. In this instance, if there is to be a tax, a package deal makes more sense.
