A report on North Korean workers in Russia, issued by the Database Centre for North Korean Human Rights, and organization in Seoul, said the Workers Party of Korea seizes 80 per cent of the wages earned by them. More money is taken to cover living expenses, mandatory contributions to a so called loyalty fund, and other donations.
In other words they work for close to nothing, which is like it was in the major industrialized countries just after the industrial revolution.
So things, basically, don't change much under capitalism, which is one of many reasons it should be abolished.
