Who's Responsible?

How would Gladwell respond to the responsibility question from September 15th?

Gladwell would say that the responsibility would lie on both the food market to tell you most of their items are corn-based and that you're not really getting a variety, but also on the consumer for failing to find out whats in it and to care about what you're eating. It's 50/50. half is the food industry's fault, but the other half is your own fault. The fact that we don't care, that we eat things without looking to see what's in it, proves that half the blame lies with us. We don't bother finding out what we put into ourselves; we definitely must accept some responsibility. But the fact that the food industry doesn't bother to let us know that, boiled down to it, everything we eat has corn in it or not, regardless to what it's supposed to be made out of. In Gladwell's view, both the industry and consumers are at fault.
