Personally, I kinda feel like people probably have perverse psychological impulses that cause us to make ourselves unhappy and discontented unless there's certain specific external constraints to control those impulses. Modern technology, in its quest to remove all constraint, eagerly removed the necessary ones.
It's sort of like fitness: way back, there was no such activity as "exercise," because everyone got enough as a matter of course (e.g. by farming, hunting, walking everywhere). Now no one has to do any of that, "exercise" is a new chore that requires willpower, so we're all getting fat.
