Why life doesn't suck even worse

Let's face it: there is a lot about life, at least for many of us, that is pretty lousy. Traffic jams, political speeches, inconsiderate neighbors -- we all have our list of things that we don't care for.

But it could be a lot worse. Well-stocked grocery stores, instant communications, anesthesia for dental procedures -- and beyond -- all of these have reduced or eliminated some of the awful things about life that our ancestors experienced. (Note that when people talk about "the good old days" things like tooth extractions without anesthesia are generally not part of the rosy picture).

Why?

Why is it that we generally don't have some of the really awful experiences that humans, no matter how wealthy, once found unavoidable?

It is because somebody, somewhere, gave a damn -- and tried to do something about it.
