The problem is structural: Not enough people do not enough work for not enough of their lives. Developed nations have 30-year-old students and 50-year old retirees, and then wonder why the shrunken rump of a "working" population in between can't make the math add up.
By the way, demographically speaking, these categories – "adolescents" and "retirees" – are an invention of our own time: They didn't exist a century ago. You were a kid till 13 or so. Then you worked. Then you died. As Obama made plain in his threat to Gran'ma last week that the August checks might not go out, funding nonproductivity is now the principal purpose of the modern state. Good luck with that at a time when every appliance in your home is manufactured in Asia.
