In Papua New Guinea, each cultural group has their own traditions, customs and religions. After independence, the government tried to allow freedom of movement and to spread Christianity and Western education. This led to class differences as some people got good jobs over others. Increasing intermarriage between cultural groups led to couples failing to pass on traditions to some children, which has led to cultural conflict. The discovery of copper provided jobs for some, but led to resentment by others. This has contributed to a civil conflict there, with law and order issues, youth gangs like the Raskols, high unemployment and urban slums
