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?
You need a certain amount of money just to cover the basics of life food, shelter, clothing. But having more money does not necessarily make you happier. It really depends on what you do with your money that creates the happiness.
Ive been doing a lot of research on this topic and I have come to believe that money CAN, in fact, buy happiness you just have to spend it on the right things.
