I find that we combine too many things into our word happiness. We combine joy, pleasure, satisfaction, excitement, comfort, etc etc. Happiness to me often loses meaning since the happiness that I strive for, satisfaction at building things is completely different than that of others. Brave new world is very much a happiness of instant gratification as well as contentment in your place in society. I would say that happiness of this sort is very unhealthy for a society that has advancement as one of it's goals.

I recommend reading about the Fun Theory:
