Chinese foodstuff is cheaper and not worthless in Japan. I know; I buy Chinese food in Japanese supermarkets all the time and I'm not the only one. It's the only way to get garlic for less than 3$ per head. It's not labeling food as Chinese that is a huge no-no in Japan (like the fish problem they had last year)
The upper class types I know think the Internet is low-class and never post on message boards or news discussions. Much like how few people here post in CNN discussion threads. It's like arguing with the lunatic fringe; why bother?
In the end, in most cases, the media manufactures consent and everyone forgets about it.
