Yes and: Surplus, and therefore overuse of, unhealthy foodstuffs (eg HFCS) is the result of pro Big Ag policies. Which are often in opposition to public health interests. So we (taxpayers) are paying to create lifestyle diseases at the same time we're paying to mitigate those same diseases.

Stop making it worse.
