>>I wouldn’t have a single problem with two million Japanese folks moving into the US, and I suspect most Americans would readily agree that it’d be the right thing and neighborly thing to do.<<
That would be a lot of neighborhoods upgraded and the biggest problem would be grade inflation at the schools.
No kidding on this — my suburban childhood neighborhood became a gang-terrorized barrio when I moved out in the late 70s to go to college.

After about 10 years, Asians started to settle in. Slowly, they took it over. Net result, beautifully manicured laws, houses painted and nice, graffiti gone, people walking in the street at night (I go back to visit from time to time as a sort of “time capsule” status thing).
Not all Asian neighborhoods are lovely, but many are. And you can compare them to places with a major street named “MLK” any day.
