Guess Japan isn't that great afterall like you often portray here online.
Let me put it into words that most of us can understand:
In the US, I make a 6 figure salary (over $150k USD a year), whereas in Japan I would be making about half the amount. So, I go where there is opportunity. I go where they pay me the most.
I've got friends from China who also came to the US for exactly that reason; opportunity. Nationalism can only go so far when one has Porsche appetite.
Guess Japan isn't that great afterall like you often portray here online.
Japan is not in question; I just happen to enjoy American Dollar, American Lifestyle, and American Society.
