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?
Money can't buy happiness if you don't have the prerequisites for being happy (honesty, integrity, etc.), but it is a tool that virtuous people can use to become even happier.
First you need to ask yourself what makes you happy. It varies from person to person. For some people, getting new friends may make them happy. For others it may be the ability to travel around the globe. And then you need to ask if money is capable of fetching you these things. In 99.99% of the cases, the answer will be YES.
