Kids Have to Work, Too
North Korean children were commonly seen performing backbreaking work. This was especially common when the country wasn't prospering economically (which is how it usually is). Children in cities were never subject to this type of labor and were mainly focused on schooling.
Gray Market Vendors
Singular vendors used to be totally prohibited, even in impoverished villages. Grey market vendors have become common practice. Many families can make some money selling candy or cigarettes.
