A lot of Japanese property was stolen during the World War II internment.
The deportation and incarceration were popular among many white farmers who resented the Japanese American farmers. "White American farmers admitted that their self-interest required removal of the Japanese." These individuals saw internment as a convenient means of uprooting their Japanese-American competitors. Austin E. Anson, managing secretary of the Salinas Vegetable Grower-Shipper Association, told the Saturday Evening Post in 1942:
We're charged with wanting to get rid of the Japs for selfish reasons. We do. It's a question of whether the white man lives on the Pacific Coast or the brown men. They came into this valley to work, and they stayed to take over... 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 do not want them back when the war ends, either.

My mom has a friend whose Japanese-American family was an exception. A family in Utah hired the entire family on as ranch hands during the war so they wouldn't be interred, and then managed their California farm, passing all profits back the family. After the war my mom's friend and her family moved back home to their farm having lost nothing.
Should I ever get caught up in some ugly wartime situation I hope I have the wits about me to do what's right and decent.
