Any happiness related to interpersonal human relationships have not likely changed much over time. Did Hamlet's unhappiness have anything to do with his standard of living? If someone asked me why people today aren't happier, then, after pointing out the hidden presumption that is at best a huge oversimplification and at worst completely wrong (are "people" really not any happier now than in 17th century France?), I'd say it's probably because people are still selfish and cruel to each other.
