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?
What money can give is temporary hapiness. If we use our wealth to help others and be a channel of blessings to less fortunate people then i can say money can be a source of hapiness because you use money in the right way.
Yes and a big yes money can buy happiness, I have never seen Bill Gate and Mark Zuckerberg never looking sad in their pictures, they are always happy smiling and waving, if that doesn't buy happiness, i really don't know what else can though. There is no more problem you can't solve with money.Even you can buy love with money.
