Sorry but they're called 'Migration Storage Facilities' not Concentration camps by the trustworthy newspaper The New York Times. This obviously means they're not concentration camps.
I'd never considered this, but of course it came down to economics- weird how often massive crimes against humanity come down to some bourgeois thief wanting to take more for themselves and willing to do anything to do it.
Just did a little reading on it, they stole 400 million (1942) dollars worth of farmland from Japanese-Americans, which is like 7 billion adjusted for inflation, and basically just gave them to agribusiness corporations.
Yeah they don't tell you in school that white Californians lobbied hard for Japanese Americans to be robbed of all their land and property, and it's a big part of why their lands weren't restored to them after the war. Like western expansion never really stopped.
I think they'd be somewhat more likely to use various schemes to enslave Hispanic migrants and citizens, given how vital Hispanic migrants are to American ag.
Not to mention deported American citizens fairly frequently, since they assume any brown person who doesn't have their license on them at the moment is illegally in the country.
