In terms of some trying to develop an economic measure of happiness, and finding people in Vancouver particularly unhappy, a particular city phenomenon that is more commonly acknowledged, Neil Remington Abramson commented as follow (reproduced with permission)
We have an economic measure of happiness, not foolproof but not new:
More money = More happiness
Maybe you could change the words around or change = to ~ or > if you thought it new enough to get published.
It’s still true about Vancouver. I have two friends who can’t find relationships with decent guys. Apparently there’s a formula: 2 weeks of bliss; 4 weeks of companionship; 5 weeks of breakdown and denouement. 11 week cycle.
