On victory gardens.
I knew about the White farmer motivation for interning Japanese Americans, but I didn't know how much the Japanese Americans produced:
Japanese immigrants and their American-born children grew forty percent of the produce in the West Coast--produce that the entire country ate. And when the exclusion zones were put into place, everyone who was 1/16th Japanese or greater by descent lost everything they had. Land they'd never get back (they were given pennies on the dollar for it after the war, but it was not returned to them), belongings they had to sell immediately or else put into storage (where an estimated 80% of it was stolen and sold; after the war, attempts to get recompense from the government for those losses required extensive paperwork and proof; people who didn't have that proof? Like, say, if they'd just spent the last few years in sheds behind barbed wire? They were threatened with extensive fines and five years in prison for their "fraudulent" claims).
They lost two hundred thousand acres of the most carefully-worked, most fertile farmland in the country. 72 million dollars in land, in 1940's dollars. And it had been taken on purpose, and that theft is the main reason that Japanese immigrants and their American-born children were interned.
Austin Anson, the managing secretary of the Grower-Shipper Vegetable Association, said:
We’re charged with wanting to get rid of the Japs for selfish reasons. We might as well be honest. We do. It’s a question of whether the white man lives on the Pacific Coast or the brown men. They came to this valley to work, and they stayed to take over. They offer higher land prices and higher rents than the white man can pay for land. They undersell the white man in the markets. They can do this because they raise their own labor. They work their women and children while the white farmer has to pay wages for his help. If all the Japs were removed tomorrow, we’d never miss them in two weeks, because the white farmers can take over and produce everything the Jap grows. And we don’t want them back when the war ends, either.
I had a friend several years ago who said something similar about the Chinese that come to work in science industries in the US, something along the lines of "They just don't have lives or the same human concerns as we do which is why they're able to outwork me."
Now, working really hard isn't a virtue, and there is an argument to be made about races to the bottom. But the solution that Whites Americans (and majority populations in other places probably do this, too) reach for is to just exclude people from opportunities on the basis of racism. "Hard-working" and "competitive" are adjectives that White Americans associate with White Americans, so I guess it creates an uncomfortable cognitive dissonance when they find they don't actually want to work hard.
