Why is the western world in unsustainable debt?

The Steyn explains in simple terms. You truly wonder what part of that lefties can't understand.

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.

This is why Steyn is, as Rhino would say, "Be-awesome."
