So never mind that there are other studies which point to different findings. More importantly: the study finds that money above $75k has no impact on "Emotional Well Being = the quality of a person’s everyday experience such as joy, fascination, anxiety, sadness, anger, and affection" however at all levels more money improves "Life Evaluation = a person’s thoughts about his or her life (on a longer time scale)." How have we decided to call the first one "happiness" and not the second one? Maybe that's how the psychologists define happiness, but it's not the everyday meaning of the word as I perceive it. Granted, English is not my first language but I would say "happiness" includes both "emotional well being" and "life evaluation", and maybe even with more emphasis on the latter when contrasted with, say, "joy" which is the one that pertains more to the short-term states, isn't that right? As a concrete not money-related example, parents of young children probably typically don't have very good "emotional well being" as defined above, but nevertheless by every account I've heard they're usually very happy, which means precisely their "life evaluation" is high.
