Happiness is related to emotions, but our emotions derive from our own needs, and as such have nothing to do with science and knowledge at all. What changes during ages is how we can realize our happiness without intruding on the lives of others. Modernity gave us more power over the world, and we might not realize that we are abusing it. I'm not even talking about the unfeasibility of giving everyone a racing car because that's what makes them happy. Even giving everyone the Western standard of living (assuming that it's what most need for happiness) is so disrupting to the Earth that it infringes on others' freedoms in ways that were not possible to the ancients.
