Subsidies

I know there are people out there who want to tax "unhealthy" foods, like soda and such. And I know there are people out there who are opposed to all forms of new taxes, even if it should have a good effect on the overall population. What I can't understand is how anyone can support the status quo:

Fixing this should be pretty obvious, and yet our dysfunctional system refuses to even touch it. We could save money and help people be healthier.
