"In May 1935 COMPULSORY LABOUR for both sexes was introduced. ...[i]t was estimated that between 200,000 and 250,000 young people had registered for "Voluntary Labour Service" ...Once ...on their register, the Nazis passed this law transforming "voluntary labour"—meaning ...forced only by hunger and social pressure to register—into compulsory labour ...Since then they have published no figures."
