There is a difference between what you are saying and saying that "money buys happiness". The research (if you read it) always maintained that there was a correlation between "happiness" (which is also not what is studied but usually 'subjective well-being') and money up to a point where the correlation leveled off. The idea being that money to that point was instrumental in securing those basic necessities you mention. What does not follow and yet is implied is the notion that if you want more happiness, just get more money.
