That reminds me, what about hypoglycemics? And folks who are under weight? Are they all going to get tax wavers or will the sick be paying a tax on their life support?
Can't you just see it? Another few pages to the income tax forms for health exemptions from the food tax.
The idea is just so impratical. Just tax all foods or no foods. And, you know a tax on all foods would never pass any legislature...nobody likes a tax unless someone else pays it.
