The Japanese are getting fat eating like Americans, thus erasing generations of healthy eating habits often extolled as particular to Japanese culture. Most will choose to see this as yet more corruption by merciless Yanks - but rather you know I'd say America didn't create the corruption but instead revealed it.
You could say that the 'genius' of America turned what was formerly seen as a weakness [the commonness of the common man] into a strength while exposing as weak what was formerly seen as a strength [the superiority of certain classes]. Those larded Japanese have taught me this.
