Traditionally the connection was acknowledged, with Socrates the prototype of the philosopher who believed that happiness, ethical living, and philosophy were inextricably linked. Obviously philosophy has come a long way since Socrates, but academic philosophers continue to give lip service to the idea that philosophy can be valuable in everyday living, if not in ethics then in processing information, critiquing arguments, and understanding the origins and limitations of ideas.
I think we've known since the time of Socrates that the practice of philosophy is not the practice of happy living. Philosophers tend to be miserable. Socrates himself chose to drink poison over moving to a different city. I think most philosophies, despite their myriad differences, agree that what people tend to want is not what philosophy will give them. Maybe some of the answers philosophy yields can be applied to increase happiness, but philosophy in practice tends to produce questions.
