Do you think there is a correlation between intelligence and consumerism/materialism?

Do you think, on average, more intelligent people feel they need to buy less things to feel satisfied? Or do you think there is another reason for feeling the need to acquire lots of possessions? Intelligent people may be more satisfied by learning. There is no question that there are people of all walks of life that buy simply to fill a void in there life. I know intelligent people who both buy little or lots, but I’m wondering what you think the overall relationship might be. Perhaps love is the factor?
