At least 27 states have taken some initiatives to reduce obesity among their residents, particularly children. The states are concerned with both health and healthcare costs. One cardiologist involved in the policy area suggested that every taxpayer be weighed at a post office once a year, when filing his or her tax return. Those whose weight is normal or who have lost weight over the past year would get a tax break from the IRS; those who are significantly overweight would pay the standard rates. Do you favor such a policy? Why or why not? If it were enacted, how would you evaluate its impact?
