DesirousOfChange,
I don't think the "happiness" scale went exactly like that. The "very happy" was at the top of the scale. After that, I believe they had choices for "happy", then "neither happy nor unhappy", then "unhappy", "very unhappy"... it was something like that.
So, you cannot infer that if you were not "very happy" then you were "unhappy". Maybe the highester earners were 41% "very happy" and 59% "happy"... who knows? Time magazine didn't give all the numbers for the rest of the scale.
Had they given that to us, then we could have seen numbers like "what percentage of highest earners were at least happy or higher"... Or, "how many of the highester earners were very unhappy"... or "how many of the lowest earners were very unhappy"... etc.
That would have been interesting to see as well.
