not at all. Happiness does not depend on money. It is more like a psychological thing which is more connected to the human minds. Don't you think so?
Some people may say YES! but not all, The thing is for me it depends for example if those people who have been poor for a their whole life then they become rich and that's what makes them happy, But for other who are rich in the first place do you think they still be happy? I don't think so...
