Taxing the unhealthy (fast) foods would allow use to gain tons of money in tax revenue, which we could use to combat other problems. I think that if we raised the prices of fatty and unhealthy foods and then lower the prices of healthy and nutritional we would be able to get people to buy the healthy food instead of the unhealthy foods. That way if a person has that $1 and he can’t afford the price of the pricey cheeseburger he’ll head over and get himself a salad which now costs that $1. Basically switch the prices of the foods, if a cheeseburger cost $1 and a salad $3, then make it so the salad costs $1 and cheeseburger cost $3.
