Not a lot of people die in the zone. Reanimates, Aliens, accident, infection, raiders, black market deals gone south, unstable explosives, building collapse, bad food - all of these things kill people on a regular basis. But, its a matter of perspective and understanding.
When infant mortality rate is only about five per one thousand, then each lost baby seems like a tragedy. When its thirty per hundred - it seems terrible and unacceptable, but you're still breeding at replacement levels and then some, and frankly - you become inured to it - these things happen, move on.
The other thing you have got to realize, is we have it easy now. At the heyday of the Event, it was chaos. Everyone has just kind of collectivism put it out of their consciousnesses because it was the epitome of anarchy Hobbes "nasty, brutish, short". The military was fighting an actual war around the world, against an enemy that could bomb anywhere and anything from orbit, the dead were rising with little local enforcement and poor coordination due to networks breaking down, some sociopaths were taking it as the end of the world and killing for canned food and bottled water...
Even the mousiest chartered accountant and quietest librarian you meet today has successfully lived through hell on earth.
Things aren't simple now - we need to replace all the infrastructure lost five years ago. We need to chose white kind of government will help us rebuild, and what ideals it should enshrine. It would be far better to say we are recolonizing the former territories of old nations, than to claim we are rebuilding the old states themselves.
We are not going to allow this dark age to last long at all. Perhaps that is the most important lesson. A few years ago, it looked like natural selection and Darwinism would reclaim its grip on humanity. Now we have some issues, but no need to accept that humans are simply prey animals in the food chain.
