Not true. Plenty of nonrich people say money doesn't buy happiness. I've known people from literally every socioeconomic level, and one thing that's very very obvious to me is that there's no actual correlation between happiness and socioeconomic status.
My favorite take on the sentiment is that money doesn't buy happiness, but it can rent it for a little while.
