Right, the study does not say exactly those things about individuals; I'm loosely extending those conclusions to the individual poster, to help my parent understand what the study means and why it suggests $75k is more happy than $200k. After all, it is not immediately obvious why $200k wouldn't be more happy than $75k- isn't $200k more money? Doesn't more money always make you happier?
