Adversarial Collaboration sounds like an oxymoron, but it’s really a useful tool, especially in those hard-to-solve problems posed by the human condition. The technique was used by two well-known experts in the fields of psychology, decision-making and economics.
Daniel Khaneman, one of my favorite authors on the subject, Matthew Killingworth and Barbra Mellers also experts on the same subjects, have recently published the results of an in-depth study on the subject of how personal income contributes to an individual’s overall happiness.

Then they plateau and increases don’t contribute to happiness. Those who start out relatively happy do not tend to reach a noticeable plateau up through an income of $400K.
Here’s an abstract of the published study:
