Does Money Bring Happiness?

The classic saying "money brings/buys happiness" is this true? There will always be two sides for this question, there are people who believe if you have more money you will be able to have and do more things (for example travel, have a nice house, clothes, cars etc.) which in turn brings happiness. And there is the other side who thinks that money does not bring happiness, their points being that a demanding workload could/would have to be done to be able to have a great amount of money, taking away from the activities you like in life. Or if you inherit massive amounts of money you won't understand the concept of a dollar or have work ethic. Because everyone knows the super star Lindsey Lohan, I thought she would be a perfect example for this. This girl was doing well, staring in Parent Trap, Mean Girls, Freaky Friday (to just name a few movies) making loads of money, but we all know how this fairy tale ends. She could/did have it all but all things went south. (http://www.people.com/people/lindsay_lohan) She has been in rehab and jail multiple times for different reasons. Not blaming those actions because she had a lot of money (correlation vs. causation) but we see many celebrities who have this same problem. They literally could buy anything but end up messing up there lives and in conclusion probably not too happy with that. They should focus of what really makes people happy like a strong marriages, true friendships, getting an education, having religious and political beliefs, exercising, being grateful, and giving back. These are all researched items that actually bring happiness, and in that list there is no reference to money. I know everyone needs X amount of money to live and take care of needs, but there are so many humans in the world who are obsessed with having a occupation where they make a lot of money, so they can become rich and therefore be happy. I think people need to rethink this equation of "happiness". So what is a "good equation of happiness"?
