Continuous improvement is what you and many others strive for. It's also what the statistics show. However, this continuous slow improvement over a large period of time (sure: combined with incorrect media coverage) leads to our world view being largely incorrect. I still thought the whole of Africa was one long hopeless story of poverty, starvation, violence and disease. When I saw the actual figures it completely took me by surprise. The world is in many aspects a lot better than we think it is.
Now obviously good news doesn't sell so I guess we'll have to learn to live with the corresponding increase of BS in the news.
