No. A little can buy some peace of mind (so you don't have to worry about losing your home or vehicle or putting food on the table) but I've known enough "rich" people who were miserable human beings to know that money can't buy happiness.
Having more money, usually creates a whole new set of problems. 1. Everyone you know wants some. 2. You hear from friends you didn't even know you had. 3. Uncle Sam wants a third of it, sometimes more. Having more money really doesn't make you happy, after all, we are all responsible for making ourselves happy, money just pads the road for an easier walk.
