There's nothing inherently wrong with food, lovin', or material goods, until you overindulge and let them warp your life.

It's basically relatively stable self-regulatory mental (and partly physiological) circuits feedbacking out of control in environments not suited for them. Problem being that we create and game these environments in modern society. On the risk of repeating myself I will point out that this is agains a case of Unfriendly Natural Intelligence.
