Well, "that's much good" is the tough part. It's not at all hard to make a totalizing model, and only a little harder to make one that's hard to disprove in hindsight (there are dozens in the social sciences) but all the existing ones I know of tend to be pretty bad at prediction. The status-seeking model is one of the better ones -- people in general seem more prone to avoiding embarrassment than to maximizing expected money or sexual success, to name two competing models -- but it's far from perfect.
