Health Care Debate

Here's an interesting question to ponder.

Food has more to do with the immediate health of an individual than trips to the emergency room or doctor's office for non-life threatening injuries or illnesses. So why is it that you have to pay for your food before you can leave the store with it but you can get a service from a doctor and pay for it later or never pay for it at all? Why can you go to jail for stealing from a supermarket but not when you steal a doctor or hospital's time or money?
