I don't know...
From my viewpoint, I'm not sure the human race, as a whole, has ever lived in better times.
Wars and political violence (except terrorism) have declined around the world since the end of the Cold War, mostly since a lot of it was about the Cold War. The proportion of the world's population living in extreme poverty has dropped from 28 percent to 21 percent since 1990, although when looked at region-by-region this figure includes decreases in some areas and increases in others.
The main problem the world has is coming up with enough resources to handle the improved living standards.
The threat of global nuclear annihilation no longer hangs over us like it once did.
It's not paradise, but it doesn't suck either.
