The Beatles said "money can't buy me love"; the Notorious B.I.G. said "Mo Money Mo Problems"; and every after-school special taught us that rich and greedy people are miserable in their hollow worlds of shiny trinkets. And now scientists have evidence that they may even have been right.

New research published in the Journal of Couple & Relationship Therapy has shown that the more materialistic a marriage, the less happy they're likely to be. The study looked at more than 1700 married couples, and it found that those with a priority on money and material goods had lower levels of marital satisfaction.

This was found when one partner was more materialistic, or even when both had an equally high level of wanting shiny new things. Couples with lower materialism tended to be happier in their relationships.

What the high levels of materialism did coincide with was being financially sound, but the money was still a bigger part of the conflict.
