Food shortage

Fox news is famous for fear mongering, Glenn Beck has been doing it for a year now. The new tactic, is the idea that there is a food shortage. The truth is that this "shortage" is nothing more than a play on the commodities market. The market creates what it wants in order to make money. So even though there is plenty of rice, they say there is a shortage and people begin to stockpile food. This talk serves to help members of the LDS church increase there amount of food storage, and feel justified in the belief that food storage is a good idea.
I am not here to say that food storage is bad, I actually think that if done in a state of calm, it can be a good idea. What I object to, is the idea of hoarding food. I also find it a bit frightening that the same people who hoard food, are hoarding guns. This seems backward to me. If the point is to take care of your family, and if we are all family, why would you need weapons.
Let's back up a bit.
If there is a situation where you are cut off from the food supply, would you really feel good sitting in your home full of food and guns, while your greater "family" is hungry?
It is essential that we take care of ourselves, so that we can take care of each other. That does not include the hoarding of food. If you come across someone who is in need, and you leave them there, knowing that you have a full pantry, what is the point?
I see the need for a 72hr kit, I even see the need for lots of water, and some freeze dried food. I do not see the point in stockpiling things like hamburger helper and mac and cheese. these items will be of no use if you do not have access to milk or meat, so you are saving this just to save it. That seems backwards and selfish.
