Can money really buy happiness?

Hell yes! The reason why people say that it won't it's because they got rich or a really good paying job, so they can buy everything they want and after a couple of months when euphoria calms down, they want something more like more friends, girlfriend, maybe even kids. The point I'm trying to make is that they KNOW how does it feel to have money, so they chase other things. You really can't explain this to anyone unless people individually experience it.
