I think we're programmed for hardship. In my experience, human beings are happiest when they're working themselves to the bone. People are more likely to feel adrift and unsatisfied when they have too much leisure time. Obstacles are good.
For me, writing post-apocalyptic novels isn't so much about exploding helicopters and fifty-megaton doomsday bombs as it is about the pleasure of dealing with the best of everything that makes us human: cleverness, grit, loyalty, and self-sacrifice.
For hundreds of thousands of years, life was brutal. It still is for a good chunk of the planet. The technology and wealth we enjoy in North America is a very new development in history, and I think we miss the challenges of day-to-day survival in our comparatively easy modern lives. Some people will even create problems if they have none.
People are tough. We're evolved for less food; more exercise; less sleep; less security; more paranoia. The irony is that we're so good at what we do. We strive for more food; less exercise; more sleep; more security; less paranoia - and we've succeeded.
