Things got better in last century.

Hans Rosling in this spectacular section of 'The Joy of Stats' he tells the story of the world in 200 countries over 200 years using 120,000 numbers - in just four minutes. Plotting life expectancy against income for every country since 1810, Hans shows how the world we live in is radically different from the world many of us imagine, and indeed has gotten better for most people.

Following the same theme, Business Insider has published "OK, Haters, It's Time To Admit It: The World Is Becoming A Better Place" by Henry Blodget. I reproduce this graph on the reduction of  war battle deaths:

Rosling demonstrates that income grew over the past two centuries and life expectancy improved, and I think that is clearly not just a coincidence. Added income allowed people and nations to live not only better but longer lives. Part of the reason was expanding education levels (here is Gapminder's show on the increase in primary education completion rates.) Here is another article on how things are getting better.
