Healthy food will never be cheaper than junk food. Producing a food item with actual health benefits takes time, money, and dedication. Pink Slime nuggets probably cost less than a penny each to make. So what's the answer? Raise prices on junk food? Unless we increase inflation by increasing minimum wage, poor people with shoestring budgets wont even be able to eat. That means more welfare, more food stamps, and a greater dependency on government handouts. The problem is and always will be a lack of proper education. No sin tax will ever change that.
