I could suggest a short story along those lines, if horror were your desire...
Instead, I suggest that you look at *The Better Angels of Our Nature* by Steven Pinker and *Nonzero* by Robert Wright. Things aren't so bad now, and they're probably getting better. Though of course even positive trends may come to an end...
(I confess that I haven't read either book yet.)
