 salads instead of fries

Fries was the only thing they were able to make well... and even that, they changed the recipe for terrible a decade ago. At the limit, you can eat their meals when you're stuck in an airport for too long or on the highway service area with nothing else... but why people in cities choose to eat there, and go again and again. I don't get it.

"blood" is not the word OK, but Saiko is right. He very certainly played the Zainichi Korean card a lot. He worked with other Korean businesses and customers in the first decades of his career in Japan. So when he reached the top in this market, people really wondered if he could expand into mainstream J-markets. He would probably have been kept aside (due to racism) during the Bubble, and he would not have been able to get Japanese citizenship earlier (Japan would reject nearly all application till the late 80's). He is accepted now because he happens to have money and valuable connections in Silicon Valley just when those once bragging "we are Nihon Ichi" are needing all that...

 poor families manage to pay 3.000USD/lerson to get to Europe, 

He certainly paid much more for 15 yrs of stay and education in California. His grandma was a farmer. When he was a teen, his father had become a gadzillionnaire owner of pachinkos, investor in banks, industries, etc.

 there aren't any parks in Japan 

Maybe in your area. Most Japanese city streets rarely get polluted by diesel as few cars pass there and they are not diesel, you often have the option to walk/cycle a little longer in the quiet backstreets. For that the situation differs from European cities (J-cities get other types of pollution). Segundo, I have walked many many times along the rivers in Osaka in the wild green areas. The water has a positive effect on pollution, cleaning the air. I went countless times to Minoh park, to the many surrounding mountain (10 minutes of train from city center). In Kobe, you just go up a few hundred meters (or 5 minutes of train), or walk on a beach. Nara is in the woods... And you still see people jogging along the biggest avenues at traffic jam hour...

Where were social services during the 15 years ? The daughter went to school or institution before that, and if she was disabled, they had records about it for school, for social security, for any other administrative stuff. That's not even the first, nor the second, nor the tenth such case that a family abucts a relative and never gets checked.

applicants whose purpose is believed to be just to seek jobs

And that's such a meiwaku ! Meanwhile, 90% of J businesses are crying that they can't find enough staff to hire. That decision benefits noone and increases existent issues. That's just one more case of a country being managed by a minority of selfish senile idiots.

If they attack people, you need to destroy the nests. Self-defense.

We usually have some (hornet nests) in the back of my parents' garden, but they are OK there, we wouldn't get stung. On year, they settled inside the house (inside the shutter box in the living room...), they were flying very close to us, I got stung (sitting down on a chair without checking...). We had to ask firemen to locate and remove them, not for revenge, but to keep living in our house.
