If I move to France, I will be expected to immerse myself in that culture and adopt it as my own.
If I move to Germany, I will be expected to immerse myself in that culture and adopt it as my own.
If I move to Japan, I will be expected to immerse myself in that culture and adopt it as my own.
...and they won't give me and my family 4-5 generations to do it in.
Except for Japan.
They won’t let you (or anybody else) move there.
Smart folks.
