In the Commonwealth of the Northern Mariana Islands (CNMI), a group of islands which the U.S. acquired after World War II and which became a U.S. territory by popular vote in 1976, the Asian garment industry has set up shop.7 Owners of factories there enjoy duty-free exports to the U.S. and can claim that their products have been “Made in the U.S.A.,” creating consumer confidence that the workers who produced them are protected by U.S. labor law.8
This time, I did manage to get my source and the reference.

Very sad and very scary...
