I think we just tend to focus on the negative stuff more because it usually hurts us so deeply. It's kind of like trust. It doesn't take much to gain it until you loose it. In the same way it's easy to gloss over the good things because the bad ones hurt so much. I still think that more people are dicks because there is less empathy in the world. People just don't care unless it's all about them. We've become selfish and have lost our compassion. Well some of us anyway!
