The Theory of Value

I think there's two primary market forces. The first one is the avoidance of pain and the second is the desire for pleasure. And so the reason i want to buy food is because of the hunger pain in my stomach. If it's tasty food, it's also the pole factor, is that going to taste good? I'm making this up. I feel dumb saying that as if i know what i'm talking abu,. There are two theories of value we can agree on but reject.
