Because the Japanese culture doesn't see themselves as perpetual "victims" like they do in Haiti or STILL do in New Orleans area after hurricane Katrina... Erroll Phillips at AT discusses a previous Japan earthquake & what DIDN'T happen:
"There was no looting or breaking into food stores
There was no time for trying to blame anyone
There was no one cutting in the front of the line to get water
There were no calls to lawyers"
Japans is a lesson for the self deluded victims across the world: take notice. Grow up. YOU are responsible for your OWN situation in life. If a disaster hits? Pull up the bootstraps and move on.
