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?
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.
Do you doubt how rich Chester Bennington is? Do you know how he died? He committed suicide, he was found to be suicide. He did it for being unhappy, he must have done it because he was stressed. If indeed money can solve all the problems, then I'm sure there will never be a case of suicide.
