You are right i should have articulated better. I do think there is a problem with happiness in that:
1) Any measurement is only an approximation
2) It is quite possible that the "pursuit of happiness" is a damaging force in humanity (it is detrimental to the environment driven by rampant consumerism with the never-fulfilled goal of being "happy")
3) That there is the possibility that it is a side effect of something else amd therefore seeking it is a fools errand.
I mentioned Bhutan as they are the only country i know of that does currently use GNH and regardless of the problems i perceive with the concept of happiness i still think using it as basic measure would change the dynamics of society in a positive way
As the article makes no reference to Bhutan, national policy, nor concludes that happiness is a worthy goal, perhaps you intended a different word?
