It was pretty obvious where you were heading, don't know why you tried to string it out so long. Are you a teacher? On the happiness point - academics will argue about almost anything. That doesn't always make it worthwhile for the rest of us to spend time thinking about. The definition of happiness however doesn't change, but of course different people have different things that make them happy, and also I agree that it is hard to measure. On the economic point - of course I agree. It isn't the sole road to happiness. I don't think that Joe Mac is actually saying this either. My understanding and opinion of the relationship of happiness and money - money can't make you happy, but a lack of money can certainly make you unhappy.
