Now, now, Morgan is right about Tokyo being crowded. My son's been there twice over the past four years. He's got photos of Train Station Attendants pushing commuters into the train so the doors can slide closed. That crowded enough for you?

You seem to like that term - "Scaremongers". Granted there are a lot of semi-informed people running around going off half-cocked. But ask older people what they have seen in the course of their lifetimes. What their hometown looks like today as opposed to when they were growing up. It doesn't matter where they come from, be it Oklahoma City, Seattle, Denver, Scranton, Billings, London, Paris, Munich or Bumble****, North Dakota, the place has grown so much you wouldn't recognize it today.
Intellectual hubris is one reason we're in the mess we're in today.
